LABORATORY STANDARD 29 CFR 1910.1450 OVERVIEW

APPLIES TO ALL EMPLOYEES ENGAGED IN THE USE OF HAZARDOUS CHEMICALS IN A LABORATORY

LABORATORY STANDARD OVERVIEW

Chemical Hygiene Plan Hazard Communication Training MSDS Sheets Chemical Storage and Labeling Emergency Procedures Personal Protective Equipment Employee Training Laboratory Safety

Chemical Hygiene Plan

Prepare written planAssign Chemical Hygiene Officer (CHO)Establish Chemical Hygiene CommitteeHold regular safety meetingsEstablish procedures to ensure a safe

working environment

Hazard Communication

OSHA created the hazard communication standard (1910.1200) to ensure the safety of the employee when working with hazardous chemicals.

This allows the employee to be informed about the chemicals they work with and how to safely use them

Health Hazards

Carcinogens Cancer causing agents Example- Gasoline

Corrosives Causes visible destruction or irreversible alterations

in living tissue Example- Toilet Bowl Cleaners

Toxic A chemical that has a lethal dose of 50 milligrams Example- Mercury

Irritants Causes a reversible inflammatory effect on living

tissue Example- Bleach

Sensitizer Allergic reactions occur from repeated exposure Example - New Carpet Odor

Physical Hazards

Flammable/Combustible Liquids Have low melting, boiling, and ignition temperatures Example- Paints and Thinners

Compressed Gasses Gases stored under an elevated pressure Example- Carbon Dioxide

Flammable Solid Causes fire through friction, absorption, and burns

vigorously Example- Sodium

Water Reactive A chemical that reacts with water to release a gas that is

hazardous Example- Potassium

Oxidizer A chemical that initiates or promotes combustion of other

materials through the release of oxygen Example- Ammonium Nitrate

shelf)

Proper Chemical Storage

1/4” lips on shelvesBottles color coded to match proper

location on shelf (Flinn System)Proper chemical labelingContainers in good condition

CHEMICAL SEGREGATION

FLAMMABLE/COMBUSTIBLE CHEMICALS ARE REQUIRED TO BE STORED IN APPROPRIATE FIRE RATED CABINETS

ACIDS ARE RECOMMEDED TO BE STORED IN APPROPRIATE “ACID” CABINET

NITRIC ACID SHOULD BE STORED IN INSULATED CONTAINER (i.e. STYROFOAM CONTAINER

FOOD AND CHEMICALS ARE NOT TO BE STORED TOGETHER

CHEMICAL CONTAINERS ARE TO BE KEPT IN GOOD CONDITION

COMPRESSED GAS STORAGE

COMPRESSED GAS CONTAINERS MUST BE SECURED TO PORTABLE CART OR WALL

CONTAINER MUST BE PROPERLY LABELEDSHOULD BE STORED IN LOW TRAFFIC OR

NO TRAFFIC AREA
