UCCS’s Compliance Method

Campus-wide Laboratory Safety Manual Maintained by EHS – available online

Laboratory Registration Updated annually by PI’s, lab managers

Laboratory Chemical Inventories Updated annually by PI’s, lab managers

Laboratory Specific Safety Plans Prepared by PI’s, lab managers – reviewed at least

annually or whenever processes change

Comprehensive Training ProgramsProvided annually and on-line

UCCS has adopted a comprehensive approach to meeting these requirements. The elements incorporated in the

comprehensive approach are:

Live Green

UCCS’s Compliance Method

Consistent message across the campus in our approach to environmental, health and safety

Allows UCCS to incorporate the requirements of several regulations into one document instead of multiple documents – reduces confusion as to which one applies in “this situation”

Focuses on the specific hazards associated with any individual lab

Allows us to incorporate not only chemical but also physical hazards into the same plan

Reduces the number of different trainings that individuals have to participate in

WHY USE A COMPREHENSIVE APPROACH?

Understanding the GHS Labels


15

Signal word: One word used to indicate the relative severity of hazard and alert the reader to a potential hazard on the label and safety data sheet. The GHS includes two signal words:

“Warning” for less severe hazard categories and; “Danger” for more severe hazard categories.

Hazard statement(s): Phrase assigned to each hazard category that describes the nature of the hazard. Examples of hazard statements are: “Harmful if swallowed,” “Highly flammable liquid and vapor” and “Harmful to aquatic life.”

Product identifiers: Names or numbers used on a hazardous product label or in a safety data sheet. They provide a unique means by which the product user can identify the chemical substance or mixture.

.


16

Other core information to be provided:

Supplier identification: Under the GHS supplier identification would include the name, address and telephone number of the manufacturer or supplier of the substance.

Precautionary statement(s): Phrases that describe recommended measures that should be taken to minimize or prevent adverse effects resulting from exposure to a hazardous product, or improper storage or handling of a hazardous product. These phrases cover prevention, response, storage, and disposal of products

Pictogram(s): A symbol inside a diamond with a red border, denoting a particular hazard class (e.g., acute toxicity/lethality, skin irritation/corrosion, etc.).

http://www.epa.gov/oppfead1/international/ghs/hazard-class.htm

17

GHS Hazard Classification

• Defined criteria are used to assign a hazard classification

– Physical Hazards 16 categories

– Health Hazards 10 categories

– Environmental Hazards 2 categories


• Labels– Symbols (hazard pictograms) with red border

• Examples:

GHS Hazard Communication


18

19

GHS Pictograms and Hazard Classes

• Oxidizers

• Flammables • Self-reactives • Pyrophorics • Self-heating • Emits flammable gas • Organic peroxides

• Explosives (1.1-1.4) • Self-reactives • Organic peroxides

• Acute toxicity (severe)

• Corrosive to metals • Skin corrosion • Serious eye damage

• Gases under pressure

• Carcinogenicity • Respiratory

sensitization • Toxic to reproduction • Specific target organ

toxicity (repeated) • Germ cell

mutagenicity • Aspiration hazard

• Aquatic toxicity (acute)

• Aquatic toxicity (chronic)

• Acute toxicity (harmful)

• Skin/eye irritation • Skin sensitization • Specific target organ

toxicity (single) • Hazardous to the

ozone layer


• These are the pictograms used in the GHS, with the hazard classes they are applied to.

• The first two rows were taken from the international transport system.

20


• As a comparison, these are the transport pictograms.

• They have different colors and backgrounds that are used to convey other aspects of the hazard.

• They do not include words on labels or markings, so hazard is conveyed solely through the pictogram.

• The symbols appear in the upper portion of the frame.

Hazard statements

• Describe the hazards covered by the GHS• Indicate the degree of severity of the hazard• Text of the statements has been harmonized• Harmonized statements are assigned to each

hazard class and category, and have been codified (a numbering system has been applied to them for ease of reference)

Physical Hazards – H2XXHealth Hazards – H3XXEnvironmental Hazards – H4XX

– Example: H318 Causes serious eye damage.

21


Other required information• Precautionary statements are required. The GHS

includes possible statements, but they have not yet been harmonized

• There are 5 types of statements: – General – P1XX– Prevention – P2XX– Response – P3XX– Storage – P4XX– Disposal – P5XX

• These have been assigned to hazard classes and categories, and codified (numbered).

– Example: P280 Wear eye protection/face protection.

22


Precautionary pictograms• Some systems may choose to illustrate

precautionary information using pictograms. These are not harmonized in the GHS.

23


Product and supplier identification

• Chemical identity required for substances• For mixtures either:

– All the ingredients contributing to the hazard of the mixture/alloy, or

– All the ingredients contributing to any health hazards presented by the product other than irritation and aspiration

• Supplier identification required on all labels, including name, address, and phone number

24


This illustrates the elements of a GHS label.

The GHS does not specify a format for the label, but

does specify that the harmonized label

elements, also referred to as the core information,

needs to be located together on the label.

Secondary Containers

Labs often pour chemicals into smaller containers for daily use – these are referred to as secondary containers

28

GHS vs NFPA Warning Labels

We will still be utilizing the NFPA labels across campus.

There are however some conflicts between the GHS and NFPA labeling systems.

Namely the hazard ratings are in reverse order.

GHS hazard ratings; however, will only appear on the SDS and not on the label.

Live Green

The NFPA label is divided into four quadrants. Each quadrant describes a specific hazard:

Blue = healthRed = flammability Yellow = reactivityWhite = special hazards

NFPA Warning Labels

29

Live Green

Numbers in the three colored quadrants indicate the degree of hazard, from 0-4:

0=Minimal Hazard 1=Slight Hazard

2=Moderate Hazard3=Serious Hazard4=Severe Hazard

NFPA Warning Labels

30

Live Green

The specific hazard in the white is abbreviated. Some of the common abbreviations are: A. OXY=Oxidizer B. ACID=Acid C. ALK=Alkali D. COR=Corrosive E. W=use no water F. The radiation symbol G. Biohazard

Accidental Release Measures

39

Determine if the spill is

Incidental Spill or

Emergency Response Spill

Incidental Spill

A spill you can handle on your own (or with the help of a

coworker)


40

Incidental SpillHow do you know if you can handle the spill? Ask yourself if you:

Have the right kind of spill cleanup materials.

Have the proper gloves, goggles and other protective equipment (i.e.: apron, face shield).

Have no exposure risk because it is a low toxicity chemical.

Have no one with a chemical exposure or injury.

Have experience or training in cleaning up this type of spill.

Have a spill that will not go down the drain.

Have spilled less than a gallon, minimizing the fire and exposure risks.


41

Incidental Spill CleanupHow do you clean up an Incidental Spill? Follow the 4W Procedure:


42

WrapWear WipeWarn

An Incidental spill becomes an Emergency Response spill if you:

• Do not have the proper spill cleanup materials. • Do not know how to safely clean it up.• Do not have your PPE (gloves, goggles, lab coat) to clean it up. • Have to clean up more than a gallon of a toxic or volatile liquid.

If any of these factors come into play and you cannot safely clean up your spill, and you should implement the Emergency Response spill procedure, described on the next page.


43

Emergency Spill ResponseIf you have a chemical spill that is too large to handle on your own, or one in which you do not have the proper cleanup equipment or PPE, it is an Emergency Response spill and you should follow these 4 steps:

1. Warn others and evacuate the area. If there is a fire, pull the fire alarm. 2. Secure the area: close the door, use caution tape, a sign, or post an

employee (at a safe distance) to warn others not to enter.* 3. Report the spill from a safe location. (Call the UCCS Police at 911 or x3111.

Give your name, call back phone number, building name, location of release, and the name and quantity of the chemical released.

4. Wait for the emergency responders from Environmental Health and Safety to provide them spill details.

*ImportantIf there is a fire or large-scale release of toxic or flammable gases, pull the fire alarm and evacuate all building occupants. Give verbal instructions to those in the immediate area to ensure they do not evacuate through the affected area of the chemical release.

Waste Management

60


After completing this module you will be able to:

1. Identify who is responsible for managing chemical waste.

2. Determine if a chemical is a “regulated” hazardous waste.

3. Identify hazardous waste types by using the CRIT (Corrosive, Reactive, Ignitable, Toxic) waste characteristics.

4. Explain proper management of various waste types, including listed waste (U, P, and F listed); universal waste (batteries, lights, computers); research chemical waste (drugs, medicine, etc.); reagent containers, and scrap glass.

History

Resource Conservation and Recovery Act (RCRA) – originally passed in 1976

– 40 CFR 260-268

• Deals with waste management• Requires cradle to grave responsibility

Proper chemical/materials waste management protects our environment and helps make our planet a healthier place to live.

The Environmental Protection Agency (EPA) has adopted a "Cradle to Grave" approach that is defined in the Resource Conservation and Recovery Act (RCRA). Accountability for chemical waste stays with the generator, which means that the waste generator is liable for any damage resulting from mismanagement of their waste, even after the waste has been shipped from the University.

That is why it is so important to properly manage hazardous chemical waste on campus

Waste Management

64

At this point you may be asking yourself, "Am I a hazardous chemical waste generator? Am I personally responsible for following these regulations?"

To see if you qualify as a hazardous waste generator, ask yourself two questions:

Waste Management

Do I use or dispose of any chemicals?Do I manage people that dispose of, or could dispose of chemicals?

If the answer to either of these is "yes," you are a hazardous waste generator and are responsible for managing your waste in accordance with institutional guidelines and state and federal regulations.

Note that these regulations also apply to any product, drug, equipment, or instrument that contains a hazardous chemical, not just laboratory reagents.

65

RCRA hazardous waste regulations apply to: Spent chemicals that were "used" for their intended purpose Unused chemicals that have expired Chemicals that are no longer useable such as those that have

become unstable and cannot be used safely Unneeded surplus Waste drugs, products, and equipment that contain hazardous

chemicals The RCRA rules do not apply to unused chemicals that are being

stored for legitimate uses. However, you may not store materials indefinitely with no legitimate use intended. In other words, you may not speculatively accumulate chemicals.

If you know your materials are waste, the next step is to determine the type of waste you have, which brings us to the CRIT waste criteria.

Waste Management

66

In this module we will be discussing not only RCRA hazardous waste but all waste streams generated in the labs:

The type of wastes covered in this module that you are likely to encounter are:

We have discussed “characteristic” wastes but another way a chemical can become a regulated waste is if it is

on a specific regulatory list. The EPA has developed several lists of regulated hazardous wastes. If your waste

type is found on any of these lists the waste must be collected for proper disposal.

F-listed

73

Take a few minutes to look at the lists below. Do you see any chemicals that you commonly work with?

F-listed wastes

F001: The following spent halogenated solvents used in degreasing (tetrachloroethylene, trichloroethylene, methylene chloride, trichloroethane, carbon tetrachloride, chlorinated fluorocarbons) and any mixture containing before use a total of 10% or more of any of the above solvents.

F002: The following spent halogenated solvents (including all solvents listed above) plus chlorobenzene, trichlorofluoromethane and any mixture containing before use a total of 10% or more of any of the above solvents.

F003: The following spent non-halogenated solvents: xylene, acetone, ethyl acetate, ethyl benzene, ethyl ether, MIK, n-butyl alcohol, cyclohexanone, methanol any mixture containing before use a total of 10% or more of any of the above solvents.

F005: The following spent non-halogenated solvents: toluene, MEK, carbon disulfide, isobutanol, pyridine, benzene, 2-ethoxy ethanol, 2-nitropropane and any mixture containing before use a total of 10% or more of any of the above solvents.

Waste Management

74

• The P-list and the U-list (unused chemical products): These lists include specific commercial chemical products that have not been used, but that will be (or have been) discarded. Industrial chemicals, pesticides, and pharmaceuticals are examples of commercial chemical products that appear on these lists and become hazardous waste when discarded. The P- and U-lists appear in the hazardous waste regulations in 40 CFR §261.33 .

Universal Wastes

Universal wastes are regulated hazardous wastes that we might not recognize as "chemical" waste. Examples include:• batteries, (recycle buckets around campus)• fluorescent lights including CFL, (Facilities collects these)• electronic circuit boards, (Facilities collects these)• surplus computers, (Facilities collects these)• aerosol cans, and (contact EHS for guidance)• switches and devices containing mercury. (contact EHS for guidance)

Other equipment may also contain hazardous materials, including lasers and carbon containing products.

Waste Management

76

These items CANNOT be thrown in the regular trash

Other Chemicals

Many of our research chemicals are not regulated as hazardous waste, but still must be collected for proper disposal. Examples of these chemicals are: visualizing dyes (ethidium bromide), Drug Enforcement Administration (DEA) controlled substances, expired pharmaceuticals, copper sulfate, and dimethyl sulfoxide.

As a general rule, all research chemicals must be properly collected and disposed of through Environmental Health and Safety.

Waste Management

77

Managing Empty Chemical Reagent Containers

Empty Non-Hazardous Chemical Reagent Containers

Non-hazardous chemical reagents are not corrosive, reactive, ignitable or toxic. Non-hazardous chemicals include agar, sucrose, most cell culture media, sodium chloride, calcium chloride, sodium phosphate and other commonly used chemicals of low toxicity.

Dispose of empty non-hazardous reagent bottles/containers through Environmental Health and Safety (for re-use or recycling) or into a recycle dumpster. Be sure to mark the container as “EMPTY”. Your empty non-hazardous chemical reagent containers cannot have more than 3% residue remaining, even if it is only water.

If you have any partially full reagent containers holding non-hazardous or hazardous chemicals, dispose of these only through Environmental Health and Safety.

Waste Management

78

Managing Empty Chemical Reagent Containers

Empty Hazardous Chemical Reagent Containers

You can save for re-use or recycle empty chemical reagent containers. Before re-use or recycle – clearly mark over or remove the previous labels.

Empty chemical reagent containers can be recycled, even if they previously held a hazardous substance, as long as the previous substance was not a P-listed waste. Containers that held any P-listed chemicals must be triple-rinsed with a chemically compatible solvent before they are considered empty and can be recycled.

Water soluble P-listed wastes can be rinsed with water Water insoluble P-listed wastes should be rinsed with an organic solvent Collect all P-listed rinse solution the way you would collect any P-listed chemical

and store for disposal through EHS

Waste Management

79

Managing Scrap Glass

Scrap glass such as beakers, jars, flasks, un-used test tubes, large glass serological pipettes, light bulbs, and empty non-hazardous reagent bottles.

Do not discard scrap glass in the regular trash because it may injure the custodial staff. Instead, place glass in a strong cardboard box, tape the lid shut and mark it "Scrap Glass." The custodial staff will pick the box up for disposal in a trash compactor.

Many wastes are prohibited from the regular trash, therefore they cannot be discarded into a scrap glass box either.

Collect "sharps" such as syringes, razor blades, scalpels, and Pasteur pipettes in a rigid plastic Sharps container. Do not discard these wastes in a scrap glass box.

Sharps containers must be disposed of in the appropriate bio-medical waste container.

• What can go down the drain?Process waste (non-hazardous, select rinsates

with EHS approval)

• What can be tossed in the trash?Paper towels, some filter paper, etc.

• What needs to be recycled?Batteries, empty aerosol cans, fluorescent light

tubes, empty (triple rinsed) chemical bottles

Collection of Hazardous Waste

Now that you know how to identify hazardous chemical wastes, let us learn about container

management rules and disposal practices.

It is very important to segregate incompatible chemical wastes into separate waste containers. Improper practices may cause fires, explosions,

toxic fumes, and regulatory penalties

Waste Management

83

Satellite Accumulation Area (SAA)

A Satellite Accumulation Area (SAA) is defined as any laboratory or room where chemical wastes are

initially generated or where chemical waste containers are stored at or near the point of

generation.

At UCCS we manage our waste containers in SAAs.

Waste Management

84

85

There are limits to how much hazardous waste you can store in any SAA

The maximum volumes that are permitted in any storage area are:• 10 gallons (37 liters) of hazardous waste per SAA• 1 quart (946 milliliters) of an acutely toxic waste (P-listed waste)• 2 gallons (3.8 liters) of flammable waste outside a flammable-rated

storage cabinet

Do no exceed any of the above limits at any time. Be sure to schedule your hazardous waste pickup before you approach these limits.

You man not store chemicals “speculatively” – this is storing them “in case”, there is a need in the future. Regulatory agencies can fine laboratories for speculative storage

Note: up to 55 gallons of waste (except P-listed wastes) are technically permitted in a SAA. However, EHS recommends limiting watete in a SAA to 10 gallons. The 10 gallon SAA limit is compliant with fire codes and reduces the potential for large spills or exposures.

Waste ManagementStorage Limits

Inspections of SAA

Weekly Inspections

Chemical waste containers are more likely to develop leaks than unused chemical reagent

containers. Chemical waste containers must be inspected weekly for leaks.

Inspect your chemical waste containers weekly by using the Hazardous Chemical Waste

Container Weekly Inspection Log and immediately resolve problems.

Waste Management

86

Inspections of SAAInspection items: waste containers are in good condition with no leakage; waste container is closed with a proper lid; chemical waste labels attached and filled out properly; no incompatible wastes stored together; no excessive accumulating (limit 1 quart (946 milliliters) of P-coded

waste); Inspection results must be documented weekly on the log provided; save inspection logs for 3 years; if you will be gone for longer than a week, you are required to either

request a chemical waste pick-up for all waste chemicals in your storage area, or find another trained staff member to conduct the inspections in your absence

Tip:If you do not have any hazardous chemical waste containers in your laboratory, you should immediately write a comment on the Satellite

Accumulation Area Inspection Log that no waste containers are in the laboratory, such as “no containers, July 1, 2010 – July 13, 2010."

Waste Management

87


To manage your experiments' chemical wastes, follow this five-step procedure:

1. Collect the waste in an empty chemical reagent bottle which is chemically compatible and has no cracks, dents, or rust;

2. Seal the container with its original lid. Do not use corks, rubber stoppers, or Parafilm;

3. Complete a Hazardous Waste Label and place it over the existing reagent label as soon as the first drop of waste is added to the container;

4. Keep the chemical waste container within eyesight at all times, otherwise you must place the container inside a locked room or a locked storage cabinet, and

5. Inspect the waste container weekly for leaks, and document your inspection in your SAA log.

Now that you have seen what you should do to control chemical waste, let us look at what you should not do.

The Five Don'tsIt is difficult to remember all the different waste management rules. There are five simple rules, however, that identify the most important waste management practices.

Don’t:

1. Discard hazardous chemicals down sink or floor drains.2. Discard hazardous chemicals in the household trash.3. Evaporate organic solvents inside a chemical fume hood (it is illegal!).4. Vent toxic or flammable compressed gases inside a chemical fume hood

(also illegal).5. Treat or destroy hazardous chemicals in your laboratory without prior

approval from EHS. These five rules should guide your day-to-day laboratory practices, and everyone who works in your lab should know them.

Before you pour anything down a drain, please check with EHS.

Waste Management

Within your designated SAA, there are rules for managing chemical wastes that relate to the following issues:

Containers Quantity accumulation limit

Segregation Adequate aisle space (space between containers)

Security Labeling

Weekly inspections Disposal

Let us look at these rules in more detail.

Container Selection and Storage

Chemical wastes are collected inside empty chemical reagent bottles or other chemically compatible containers. Follow these rules when selecting an empty chemical reagent bottle to collect chemical waste:

Select an empty container in good condition (no cracks, rust, dents or holes).

Check the container's lid to make sure it fits properly and it is the proper type (no corks, rubber stoppers, or paraffin).

Rinse empty containers thoroughly before adding an incompatible waste to it.

Collect waste in chemically compatible containers (no acids in metal containers).

Keep containers closed at all times except when adding or removing wastes.

Ensure that the container has the proper UCD chemical waste label as soon as the first drop of waste is added to the container.

Waste Management

91

Segregation

When different types of waste mix, anything can happen! Here are some important segregation rules:

Do not store oxidizers with flammable liquids.

Do not store acids with bases.

Do not store water-reactive chemicals (sodium hydride) next to aqueous materials or corrosives.

Do not mix hazardous chemicals with infectious agents or radioactive isotopes waste without the approval of the EHS Department.

Store incompatible chemical waste containers inside separate storage cabinets. Otherwise, place incompatible containers which are stored together into plastic pails for secondary containment (large enough to hold entire contents of container).

Waste Management

92

Segregation

Note: Halogenated solvents cost 2.5 times more to dispose of than non-

halogenated solvents because halogens form acidic gases when incinerated. Researchers are asked to keep halogenated solvents segregated from other solvents in the laboratory.

Some chemicals can be combined. See the next slide for

guidelines regarding combining chemical wastes. Flammables and oxidizers cannot be stored together. Oxidizers must be stored in secondary containment when stored

with other lab chemicals.

Waste Management

93

The following guidelines need to be followed when collecting chemical wastes in a waste container in the laboratory:

1. Clean flammable solvents (alcohols, acetone, acetonitrile, xylene, etc.) may be collected together inside the same waste container.

2. Acids must be collected separately.3. Bases or caustics must be collected separately.4. Halogenated solvents (chloroform, methylene chloride, carbon

tetrachloride) must be collected separately.5. Heavy metals (arsenic, barium, cadmium, chromium, lead, mercury,

selenium, silver) must be collected separately. Do not mix heavy metal wastes with organic solvents.

6. Toxic liquids (phenol, acrylamide, formaldehyde) must be collected separately.

7. Solid chemical wastes are collected separately from liquid chemical wastes.

8. Solid debris that is contaminated with highly toxic or carcinogenic chemicals must be collected separately.

Waste Management

94

Space Rules

To facilitate spill cleanup, always maintain at least 3 feet (91 centimeters) of aisle space to reach the chemical waste containers in your laboratory.

Do not store laboratory supplies, carts, or equipment in front of your chemical waste containers.

Waste Management

95

Security Rules

You are responsible for the waste you generate, even if someone else handles it.

Chemical waste containers must always be under your control. The waste container must be under visual observation at all times. If no one is present, waste must be under lock and key. This ensures that incompatible wastes are not commingled into your waste container by untrained or new employees.

Waste Management

96

Labeling Chemical Waste Containers

Each chemical waste container must be labeled with a chemical waste disposal label as soon as the first drop of waste has been added to the container.

When labeling an empty chemical reagent container for waste storage, ensure the following:

Eliminate existing information on the reagent container. Attach the waste label securely (over existing reagent label). Estimate chemical concentrations based on volume; Write the percentage of water in the waste; No abbreviations - spell chemical name completely. Complete all sections of the label carefully except leave the date blank

until the container is full and ready for pick-up by EHS

Waste Management

97


• Be sure to collect in compatible container with lid – use secondary containment

• Affix proper label • Biology and Chemistry check with your lab

manager regarding accumulation• Others can request waste pick-up when a

container is full or you are no longer going to be adding to it – use the form on the EHS website

• Campus pick-up occurs 2x per year

Disposal Guidelines

When you approach the quantity limits of chemical waste or you are finished generating waste, it is time to prepare it for disposal.

• Fill out the UCCS Hazardous Waste Removal Request.

Sink Disposal Prohibited

Generally, the disposal of chemical waste down a drain is prohibited. However, there are some exceptions. Please contact EHS before drain

disposing any chemicals.

Common Concerns

During routine waste management audits, frequently observed compliance concerns are:

Lack of on-the-job and refresher training. Waste container missing chemical waste label. Open chemical waste container (lid missing). Open waste container with funnel sitting inside it. Use of improper lid (cork, Parafilm, rubber stopper) to seal chemical

waste container. Waste containers not inspected weekly for leaks (SAA form not

completed).

Waste Management

Note: Researchers are not allowed to treat or destroy hazardous chemical wastes in the laboratory without permission from Environmental Health and Safety.

101

Hazards

Up to this point we have discussed hazardous materials management and waste management. Besides hazardous materials/waste there are a number of other types of hazards present in the laboratories. We will now take a few minutes to quickly review the management practices associated with some of these other hazards.

102

Module 4: Other Hazards

Types of Hazards• Mechanical• High Energy• Lasers• Magnetic Field

Generators

Physical Hazards

• Compressed Gases

• Power Tools• Noise

You need to review the lab operations with your Principal Investigator (PI) to determine which of these hazards may be present in your lab. Once you identify the hazards – you then need to review appropriate safety precautions for each hazard.

103

Biological Hazards

Biological hazards are substances or agents (e.g., viruses, bacteria, spores, fungi, bloodborne pathogens, prions, or toxins from a biological source) that pose a threat to the health of living organisms. Biological hazards can include human bodily fluids and tissues.

Bloodborne Pathogens

• Take on-line training at the EHS website

• BBP Exposure Control Plan• Wear proper PPE when

exposure to bodily fluids is likely


106


• Proper handling and disposal of sharps

• Hepatitis vaccine

• Disinfection and clean up


107

Biological Safety

Varying degrees of risk are associated with exposure or infection. For infectious agents, these risks are categorized by "risk groups" (RG) based on the potential effect on a healthy adult human, taking many factors into account, such as pathogenicity, mode of transportation, and the availability of effective treatments or preventive measures.

108

Biological Safety

Risk Group Description Example Organism

Risk Group 1

Agents that are not associated with disease in healthy adult humans.

B. subtilis, S. cerevisiae (Baker's yeast)

Risk Group 2

Agents that are associated with human disease which is rarely serious and for which preventive or therapeutic interventions are often available.

S. aureus, G. lamblia, Adenovirus

Risk Group 3

Agents that are associated with serious or lethal human disease for which preventive or therapeutic interventions may be available (high individual risk but low community risk).

B. pseudomallei, Hantaviruses

Risk Group 4

Agents that are likely to cause serious or lethal human disease for which preventive or therapeutic interventions are not usually available (high individual risk and high community risk).

Cryogenic HazardsCryogenic liquids are extremely cold, with a normal boiling point below -130° C (-90° F). Substances commonly stored and transported at cryogenic temperatures include argon, helium, hydrogen, nitrogen and oxygen.

Cryogenic liquids present several hazards, including:

Laboratory Hazards

Extreme Cold HazardAsphyxiation HazardToxic HazardsOxygen-Enriched AirExplosion due to rapid expansion

Due to the high risk of asphyxiation, you should never attempt to clean up a large cryogenic liquid spill, particularly in a closed indoor area. If there is a spill of cryogenic liquids in your lab, evacuate and close off the area, and call 911 or x3111 for assistance.

112

Compressed Gas CylindersAll compressed gases are considered hazardous because of the high pressure of the container; a rapid pressure change can create a hazard. For example, if a gas cylinder falls and the valve is damaged, the immediate release of pressure can force the cylinder to move, sometimes with enough force to go through walls.

Laboratory Hazards

Gases can be: asphyxiants by displacing oxygen, corrosive, highly toxic, flammable, oxidizing or highly reactive.

113

Energy

Many forms of energy exist in lab settings and can present a hazard, even seemingly innocuous forms of

energy such as light. Always be on the lookout for stored energy such as spring loaded systems

(including syringes), hydraulic devices, capacitors, and battery operated systems.

Laboratory Hazards

• Primary responsibility for safety in the lab lies with every individual

• PI’s and lab instructors are responsible for enforcing guidelines in the labs

• Safety should become an integral part of our daily activities
