Legal Requirements - HSA

• The HSA Refer to any substance, in gas, liquid or solid

form, which has the potential to cause harm, is

referred to as a hazardous or dangerous substance.

• Agents can be considered hazardous not only

because of what they contain (i.e. in the shape of a

constituent or chemical ingredient) but because of

the form or the way in which they are used at the

workplace, e.g. hot water used as steam can cause

severe burns and adequate control should be

available to prevent such exposure.

7


Legal Requirements

• Employers must ensure a safe working

environment.

• They Must:

– Determine which hazardous substances

are present.

– Provide prevention and control of

exposure to the hazardous chemical

agents.

• Eliminate the risk.

– Specify protection and prevention

measures.

• Provide PPE.8


Legal Requirements

• They Must

– Where necessary provide

Health Screening.

– Provide arrangements to deal

with accidents, incidents and

emergencies.

– Information, training and

consultation.

Chemicals Awareness

• Introduction

• Legislation


• The Skin

• Chemical Gloves

• Why Gloves Fail


• Review of MSDS10


What We Need to Know

• What is the name and classification

of the chemical.

• The concentrations we will be

using.

• We need to read and understand

the SDS.

• We must carry out a Risk

Assessment and update all relevant

SOP’s.

11



• Chris Packham. Very important – when carrying out

a risk assessment it isn’t what is on the safety data

sheet but what is present when you use the

chemical(s). There are literally thousands of

chemicals that have not been classified as

hazardous (i.e. have no risk phrase, or no hazard

statement) and will therefore not usually appear on

the safety data sheet. They can be sensitisers (over

4,000 at the last count), certainly many will be

irritants and some may even have systemic toxic

properties. Furthermore, they may not be present

in the original chemical as supplied but created due

to the way they are being used.

12



• We need to Know

– The permeation and

degradation times of the

chemical or chemicals we are

handling versus the glove we

are proposing to use.

– When and how to dispose of

the contaminated glove.

– We need to carry out tool box

talks on the above with all the

related users.

13


• Irritant

– Is a chemical that is not corrosive, but can cause

reversible inflammatory effects on living tissue at the

site of contact (e.g. strong solvents).

• Sensitiser

– Is a chemical that will cause an allergic reaction in a

substantial number of exposed people (e.g.

isocyanates).

• Corrosive

– A chemical that causes visible destruction of, or

irreversible alterations in living tissue by chemical

action at the site of contact (e.g. hydrochloric acid,

hydrofluoric acid ).

Effects of Chemicals on the Body

14



• Carcinogen

– A chemical that causes or has the

potential to causes cancer.

– Is a chemical capable of causing changes in

the DNA resulting in uncontrolled growth

of cells growth or cancer. They are

insidious because no immediate harmful

effects are felt. Latency period can be

from 20-30 years.

– Usually results from chronic exposures.

– (e.g. asbestos, formaldehyde).

15



• Reproductive toxins are those that have

an adverse effect on reproductive system

including: fertility, gestation, lactation and

general reproductive performance.

– Mutagen

• A chemical that damages

chromosomes (e.g. benzene).

– Teratogen

• A chemical that causes birth

defects (e.g. thalidomide).

16


Chemicals to Consider

• List

acrylicacid, aflatoxins, aniline arsenic, benzene, benzo(a)pyrene, cadmium, carbondisulfide, chromic acid, chloroform, chloroprene, N,N-dimethylacetamide, dimethylformamide (DMF), Dichloromethan(DCM),dimethyl sulfoxide (DMSO), dinitrooctylphenol ,di-sec-octyl-phthalate, diphenylamine, dithane, estradiol, 2-ethoxyl ethanol, 2-ethoxyetyl acetate, ethyl thiourea, 2-ethylhexanol, formaldehyde, formamide, glycol ethers, halothane, hexachlorobenzene, hexafluoroacetone, hydrazine(s), iodoacetic acid, karathane, lead compounds, mercury compounds, 2-methoxy ethanol, 2-methoxy-ethylacetate, methylchloride, N-methyl-2-pyrolidone, nitrobenzene, nitrousoxide, phenol, polychlorinated and polybrominated biphenyls, propylene glycol, monomethyl ether, propylene glycol, monomethylether acetate, propylene oxide, systhane, TOK(herbicide),toluene, trichloroethylene, vinyl- chloride, xylene

17


Routes of Exposure

• Inhalation

– Is the most common route of exposure, lungs are designed for maximum transport and adsorption of vapors.

• Dermal

– Is the second most common route of exposure, water soluble chemicals and solvents can pass through the skin.

18


Routes of Exposure

• Ingestion

– Can occur through food

contamination, eating,

drinking in the lab, poor

hygiene.

• Injection

– Can occur through injury and

needle sticks.


Routes of Exposure - The Body

• Regardless of the way a chemical

enters the body , once it is in it can

be distributed anywhere in the

body via the bloodstream.

• Certain chemicals may target

certain organs like the, liver, eyes,

lungs etc.


Acute Toxins

• Acute toxicity is the ability of a chemical

to cause harm after a single exposure.

– A good of example of this is an Acid

Burn on the skin.

• These include: acrolein, arsine, chlorine,

diborane, diazomethane, hydrogen

cyanide, hydrogen flouride, sodium

cyanide, dimethyl mercury, etc.

21


Chronic Toxicity

• Harm occurs through repeated

usually lower levels of exposure.

This includes most carcinogens,

reproductive hazards and some

heavy metals. Many have a long

latency period of 20 years and more.

Generally the longer the exposure

the greater the hazard.

22


Factors Affecting Toxicity

• The potential for toxic effects is

determined by the dose, the duration,

the frequency and the route of exposure.

• Exposure to small amounts of highly toxic

chemicals can be a greater danger to

health than exposure to larger amounts

of less toxic chemicals.

• Once off exposure of short duration are

of less concern than multiple exposures

over long durations.

23


Medical Surveillance

• Synergistic effects - the combination of

the toxic effects of two substances may

be significantly greater than the toxic

effect of either substance alone.

– For example lung cancer is much higher in

smokers who have be exposed to Asbestos ,

than people who have smoked and not been

exposed to asbestos.

• The use of certain chemicals at particular

exposure levels require the participation

in a medical surveillance program.

Skin

• Introduction

• Legislation


• The Skin

• Chemical Gloves

• Why Gloves Fail




Skin

• Christoph Wilhelm Hufeland (1762-1836). We must consider our skin not merely as a passive cover against rain and sunshine, but as one of the most important organs on our body, without whose unceasing activity neither health nor a long life can exist and whose neglect is a source of countless illnesses and early deaths.

27


Our Skin – Stratum Corneum

– The out layer of our skin is called the stratum corneum. New skin is made in the lower layers and moves to the surface every 4 weeks.

– The Layer can be 0.002m

28


How Our Skin Works

• Our outer cell are bound

together by an emulsion

which is a mixture of oil and

water.

• This ‘natural skin oil’ controls

water evaporation from the

skin’s surface.

29


How Our Skin Works

• Bo Forslind a US Professor

referrers to this 0.002 mm

thick layer as a complex layer

of fats and water that stops

us from dehydration.

• If someone dies from 3rd

degree burn, It is this layer

that gets damaged resulting

severe dehydration.

• It can also be removed by

solvents that come in contact

with our skin.

30


Our Skin - Dermis Layer

– Is a thick inner layer of tissue.

– It contains a network of Blood vessels nerve ending, hair follicles and sweat glands.

– It carry’s all the nutrients to the outer epidermis layer.

31


Irritant Contact Dermatitis

• Skin Irritants

• Skin irritants are comparable to a chemical burn. It acts by eroding or burning the outer protective layers of the skin and exposing the lower layers.

• Common irritants such as wet working, cutting oils, solvents and degreasing agents can remove the skins outer oily barrier layer and allow easy penetration of hazardous substances through the skin causing the lower layers of skin to become visible and inflamed.

32


How are skin problems caused

• The protective layer is normally worn away, but it is constantly being regenerated.

• The problem arises when the rate of damage or wear exceeds the rate of regeneration.

• There are 2 forms of dermatitis, contact irritant dermatitis and allergic contact dermatitis.

33


• Allergic contact dermatitis is a result of someone becoming sensitised or develops an allergic reaction to a substance.

• The sensitisation period of an allergy, can vary from a number of days to months or even years.

• Some examples of this; is an allergies to proteins and corn starch in latex Gloves.

Allergic Contact Dermatitis

34



• Irritant Contact dermatitis ICD can be thought of as dermatitis resulting from direct damage to the skin by a chemical over a period of time.

• One concept is, every time the skin is exposed to an irritant damage is done.

– The damage will depend on:

1. Strength of the chemical.

2. The Duration of exposure.

3. The frequency of exposure.

35


ICD – Skin Recovery

• The skin will recover from exposure to a chemical over a period of time.

• If it is not given a chance to recover the damage will accumulate.

• This damage will not be visible to the individual.

• The skin will then reach a tipping point where it looses its ability to heal and offer resistance to the irritant.

• This is the tipping point where the skin begins to show symptoms of damage i.e. Dryness, cracking, flaking, redness etc.

• The user has developed full blown Irritant

Contact Dermatitis ICD.36


ICD – Skin Recovery

• The skin will begin healing if the irritant is

removed

• It is important adequate time is given for this

healing to take place

• If adequate time is not allowed to heal the skin

may loose (in extreme cases) it’s ability to heal

and he/she may develop Chronic Irritant

Dermatitis

37



• Skin Recovery

• The break-through threshold occurs only after a long

period of exposure (up to several years).

• The reaction of person is to try to identify something

that has happened recently, when in reality it is a

result of long term build up of invisible damage.

• It must also be stressed that irritant contact

dermatitis generally results from exposure to wide

range of irritants that are used in home and at work

which cumulate together.

38


ICD - Effects

• Once the threshold has been reached there will be a

permanent weakening of the skin resulting in a

heightened predisposition to suffer from ICD in the

Future.

• The Skins ability to resist penetration by other

substances will also be reduced.

• We should also remember that damage from an

irritant will reduce the levels of exposure needed for

an allergic reaction to take place also and possibly

increase its severity.

39


ICD – Systemic Toxicity

• For example, This can occur if we are handling volatile

solvents like acetone

– Wearing a standard disposable Nitrile Glove and

submersing our hands and fingers in the solvent.

– Not operating under a fume hood or wearing a

protective mask

• The vapours fill the air.

• The liquid break through the glove in around 20 seconds

• We are now adsorbing the substance via or lungs and skin

• We need to be aware of this when we take into account

inhalation work exposure limits of substances

40


Ways to Combat ICD

• Try to Use the least Irritant substance

• Work in such away that contact between the skin and the irritant is avoided or minimised so far as is possible.

– Wear appropriate selected gloves.

– Change out the gloves at the recommended times.

• Ensure that the skin has sufficient time to recover before permitting contact with the same or other irritant chemicals.

41


Wet Working

• You can loose up to 750ml of water

through your skin each day.

• When you wear a waterproof glove

this water cannot evaporate and the

skin becomes hyper hydrated.

• This enclosed micro environment

inside a glove will reduce the skins

barrier performance and actually

increase the possibility of irritant and

allergic damage to the skin should the

glove fail.

42


Wet Working

• Dermatologist consider water an

irritant and wet working as the most

common cause of Skin Disease.

• This will increase the risk and rate of

chemical penetration into the skin.

• German laws require a cotton liner

glove to be worn under a waterproof

glove if the glove is worn for more

than 2 hours in a 8 hour day.

43


Chemical Gloves

• Introduction

• Legislation


• The Skin

• Chemical Gloves

• Why Gloves Fail




Why Gloves Fail

• Misuse

• Physical Damage

• Degradation

• Permeation

45


Misuse

• The wrong glove for the task.

– E.g. mechanical and leather

gloves for handling drums of

chemicals.

– Disposable gloves for a

mechanical task where there

is a possibility of coming in

contact with a chemical

• Wrong Size glove.

46


Misuse - Wicking

• Cotton lined glove must be treated with caution when Handling chemicals.

• The fibres from the fabric could penetrate the outer nitrile coating.

• These are usually produced by dipping a fabric woven glove into a solution of nitrile, PVC etc.

• Once the fabric is in contact with the chemical it acts as a reservoir, ensuring maximum skin contact.

47


Physical Failure

• AQL – Actual Quality Level

• Penetration means the

macroscopic seeping of a

substance through small pin

holes in a glove. It happens when

the glove has a leak.

• For this reason, KCL carries out a

100% control for chemical

protective reusable gloves.

Level AQL Example

1 4 4 faults per 100

2 1.5 1.5 faults per 100

3 0.65 0.65 faults per 100KCL standard

48


Degradation - Swelling

• Direct damage to the glove material by the chemical. For example paint thinners will degrade a natural rubber glove.

• Swelling is not a part of the EU Standard EN374 of chemical glove testing

• Swelling up to

– 6.9 % Resistant

– 14.9 % Partially Resistant

– 15% Not Resistant

49


Chemical Gloves

• Gloves are a temporary barrier between the chemicals we handle and our skin.

• In some cases they provide a barrier for seconds and in other cases its days, weeks and even months.

• Gloves are made from a variety of compounds and certain compounds are more effective against certain chemicals.

• There is no glove that is unaffected by all

chemicals.

50


Permeation - Background

• Permeation is a transfer of a chemical at the molecular level through the glove wall.

• The chemical is emitted into the glove interior as a vapour.

• Permeation does not result in any change to the gloves appearance– Its feels normal and is undetectable by the user

• When it comes to chemicals we need to know what is the permeation breakthrough time (BTT) of that chemical is versus the particular glove we are proposing to use.

51


Permeation - Process

Chemical

How many minutes???

Glove

How do you know if

the glove is

working??????

Skin

At what point is the

chemical in contact

with your

skin????????

52


Permeation – Combined Chemicals

Acetone

How many minutes???

Glove

Lets assume that

somebody is wet

wiping a contaminated

( blue ) surface with

Acetone ( red ). The

listed permeation time

of the powder

contaminant is

480mins, but Acetone

is 30 seconds!! The

result is permeation of

both in 30 seconds!!

Skin

Contaminant

53


Permeation - Time

• A chemical can permeate through a protective glove at a molecular level within seconds.

• The clock starts from first contact with the chemical.

• Once the chemical has permeated through the glove the path is opened and all other contact chemicals can leach through at the same rate.

54


• The size of the gloves.

• The glove material and thickness.

• The type and concentration of chemical.

• Is the gloved splashed or submersed in

the chemical.

• The exposure time.

• The mechanical strain.

– Type of work.

• The synergy of chemicals.

• The age of gloves.

• The working temperature.

Permeation - Factors That Effect It

55


Permeation - Temperature

• EN 374 requires that

Permeation break

through tests be carried

out at 23°C ±1°C.

• Actual temperature

inside a glove tends be

around 35°C.

• Permeations times can be

reduced by 25% or more

at higher Temperatures.

Chemical BTT @ 23ºC BTT @ 35ºC

N-Butanol >480min >240min

Diethylamine 60 min 6min

Dipenten 480 min 36min

Isobutanol 240 240

Methyl Ethyl Keton

1440 240

56


Permeation – Clock Starts

• Permeation starts from the first contact

with a chemical.

• It continues regardless whether or not the

glove is in use.

• The glove will appear as new, and it is

often difficult to persuade users that it

must be change out.

57


Additional Considerations

1. Mechanical Strength of Glove versus the Task.

2. Dexterity .

3. Cuff Length.

4. Grip.

5. Cut and puncture Resistance.

6. Electro Static Requirements.

7. Temperature of Product.

8. Bacteriological Risk.

9. Radioactive Contamination.

10. Cleanroom Compatibility .

11. Sterile Requirements .

12. Possible Silicone Free Requirements.

13. If working with two or more chemicals, take the lowest permeation time of two chemicals .

58


HSE Study on Printing Workers

• The prevalence of occupational dermatitis amongst

printers in the midlands in the UK. Approximately

2600 members of the Graphical Paper and Media

Union (GPMU) living in Nottinghamshire were sent

a self-completion questionnaire.

– Findings:

• 41% of the work force reported that they

had suffered a skin complaint at some time

and 26% had a current skin problem on one

or both of their hands.

• 90% of the control group wore PPE such as

gloves.59

60



• One quick way to tell if a glove

offers protection against a

chemical or biological hazard is

to identify the category (l,ll,lll)

into which the glove fits.

61


• Protective gloves against minimal risks EN420:2003

• For gloves of simple design offering protection from low level risks

• For those chemicals, should the gloves fail, there will be no

significant damage to health of the user.

• If the glove should fail the damage will be minor and the effect is

reversible.


Category IMinimum risks

Low protection requirements

62


• Protective gloves against intermediate Risk

– Some gloves can also comply with specific applications like

1. EN511:2006 Cold

2. EN407:2004 Contact heat under 100°C

3. EN374-2:2003 Water tightness

4. EN388:2003 Mechanical risks

5. EN 511:2006 Protective gloves against cold

6. EN 407:2004 Protective gloves against thermal risks


Category IIMedium Risks (standard)

Protection against mechanical

Risks.

63


• For serious or potentially life threatening risks and

where the danger is irreversible.

• E.g. For protection against chemicals that can result

in Irritant Contact Dermatitis and Allergic Contact

Dermatitis.

• For anything other than minor hazards, e.g. water

mild detergent, mild acids etc we should only use

category III gloves.


Category IIIHigh risks

64


• Symbol

• The glove will have achieved a minimum of 30 mins

protection against 3 of the 12 listed chemicals on EN374.

• Every batch of the glove manufacture at KCL is tested

for:

– Elongation

– Cut Resistance.

– Tear Resistance.

– Puncture Resistance.

– Chemical Permeation.

SDS Declarations

• How do I recognise hazardous substances?

• Suppliers are required by law to identify the hazards of the chemicals and products they provide.

• The warning signs and R-phrases on the container and the safety data sheet will help you to identify chemicals causing harm to the skin and to the health of the user.

• Before using a chemical, always read the label on the container and consult the safety data sheet.

• Consumer products, such as those used for hairdressing, are unlikely to carry R-phrases or warning signs.

68


DCM - SDS

69


Example of Risk Symbols

• Avoid contact with skin (S24 ).

• Wear suitable gloves (S37).

• Irritant to skin (R38).

• May cause sensitisation by skin contact (R43).

• Toxic in contact with skin (R24).

• Very toxic in contact with skin (R27).

• Causes burns (R34).

• Causes severe burns (R35).

70


Try To

• When in doubt about double glove.

– Wear a disposable glove under a reusable glove.

• Hydrofluoric.

• Avoid sharing reusable gloves.

• Dispose of reusable gloves daily.

• Inspect for nick, cuts and pin holes.

• If in doubt throw it out.

– Dispose of used gloves as chemical waste.

• Wash your hands thoroughly after wearing gloves.

– Use skin care products if possible.

71


Cross Contamination & DonningCross Contamination & Donning

Typical Glove Material

• Nitrile

• Latex

• PVC

• Neoprene

• Butyl

• Viton

• Laminate

75


Additional Standards

• EN1149 – Protection against static electricity.

• EN 421 – Protection against ionising radiation.

• EN374 – Protection against bacteriological risk.

• ASTM 1671:2001 Protection against viruses.

76


Medical Grade Gloves - Manufacture

• Medical Grade Gloves only have to be tested once to meet EN455

• The are pressured tested to give AQL values.

• In the case of the of powder free disposable gloves they are

chlorinated to remove powder from the manufacturing process.

• There is nothing in the standard that stipulates they are

manufactured in a hygienic manner or have a certain percentage

powder free content.

• If you start to see you bacteria counts increase, think about your

gloves.

• The same applies for ISO class 7&8 cleanrooms where there is an

increase in Dust particles.

77


Cat I Disposable Gloves- Manufacture

• Cat I EN374 disposable gloves go through the same testing as

EN455. But they have also achieved a 30 min permeation time

against one of 12 test chemicals on the previous list.

• Ageing tests are also carried out on the glove.

78


Cleanroom Gloves

• Cleanroom gloves get additional washing in

deionised water.

• Cleanroom gloves are double or treble bagged

• Cleanroom gloves are typically used in an ISO

Class 6 or below cleanroom.

• ISO Class 7, 8 and require minimum of powder

free gloves.

79


Sterile Gloves

• Used where there is a risk of bacterial,

viral or fungal contamination

• Gloves are packed per pair.

• Gloves are sterilised with Gamma or

ETO radiation

80


Things to Consider

Chemical Gloves

1. Check the glove for tears or pin holes

2. Select the glove for the work in hand, and discard within the safe time, to avoid contamination to the skin.

3. Don and doff the gloves safely without contact with the outer surfaces if contaminated.

4. Try to ensure that there is no cross contamination, or contamination of areas, objects, equipment.

5. Wash hands thoroughly, and apply after work creams at the end of the day.

81


Disposal of Gloves

• Gloves contaminated with hazardous chemicals are hazardous.

• Glove waste and must be disposed of accordingly.

• Nitrile gloves, if incinerated, can release cyanide!

• PVC (vinyl) gloves, if incinerated can release dioxins!

• Viton, if heated beyond 200ºC will release hydrofluoric acid, either as liquid or vapour!

Food for Thought

• If your skin exposure risk assessment is based on the safety data

sheet, then there is a very real possibility that it is wrong!

•If you do not know the Permeation Times of the gloves you are using

versus the chemicals you are handling then your colleagues could be

at risk.

•If you are using category I gloves for a category III application, then

your workforce’s health could be at risk.

•If you believe that as airborne exposure to a sensitiser is below the

WEL then your workforce is safe - you may be wrong!
