Recommendation 9:


Safe work practices are critical in keeping solvent emissions to a minimum. Safe practices that help to minimise emissions are detailed below and must be followed.


SAFE WORK PRACTICES
location of the degreaser tank (it should be located away from draughts such as open windows or doors) (Standards Association of Australia, 1983);

keeping tanks closed when in use and idling (Standards Association of Australia, 1983);

minimising turbulence during lowering of the workload into the tank by reducing the rate of introduction (Standards Association of Australia, 1983);

proper placement of the parts to be degreased in the basket thus avoiding solvent collecting in the parts;

sufficient time in the freeboard zone to allow adequate draining/drying time (Standards Association of Australia, 1983);

routine equipment inspections to locate leaks or any other problems (Standards Association of Australia, 1983);

avoiding splashes or spills during solvent filling, draining or transfer operations;

prompt clean up of spills;

All ignition sources should be eliminated in areas where high concentrations of vapour may accumulate;

frequent cleaning of the tank to prevent buildup of caked material at the bottom (Standards Association of Australia, 1983). Regular maintenance will reduce the need for entry into the tank during cleaning;

the requirements of AS 2865-1995 “Safe Working in a Confined Space” (Standards Australia, 1995) should be conformed to if entry into a tank is necessitated for cleaning purposes. A number of fatalities have been reported when people have entered tanks to clean them.




17.2.5Personal protective equipment


Personal protective equipment (PPE) is used to minimise exposure or contact to chemicals. PPE should be used in conjunction with other engineering controls and not as a replacement.

Protective gloves help to prevent dermal exposure to trichloroethylene. It is important to select gloves that are resistant to the chemical exposed and are appropriate for the duration of exposure. If swelling of the gloves occurs they should be discarded.


Recommendation 10 :


It is recommended that when selecting gloves the manufacturers and suppliers information be used as gloves made of the same generic material can differ due to differences in manufacture. For formulated products, gloves should be selected on the basis of the component with the shortest breakthrough time. Protective gloves should be used when skin contact with trichloroethylene is likely, such as during loading and unloading of work parts from the vapour degreaser, during cold cleaning, clean up of spills or during other work processes where splashes are likely.

Protective clothing which includes protection of the arms, legs and feet should be worn where exposure of trichloroethylene may occur. Eye protection is recommended when vapours may be generated or when splashing may occur. Personal protective equipment should be in accordance with the relevant Australian standards.

If cleaning of degreaser tanks involves entry into the tank respiratory protection is required. A suitable supplied-air respiratory protective device complying with AS/NZS1716 (Standards Australia & Standards New Zealand, 1994) should be worn.

17.3Hazard communication


Trichloroethylene is a hazardous chemical and employers are obliged to provide employees with MSDS, training on the proper use of trichloroethylene and information on the health hazards of the chemical and ensure that all containers used at work are adequately labelled.

17.3.1MSDS

Recommendation 11:


It is recommended that suppliers significantly improve and amend their MSDS where necessary in order to rectify deficiencies identified in the assessment.

17.3.2Labels


A large number of deficiencies were identified in the labels provided for assessment.

Consumer Products

The labels on products available for domestic use did not comply with the requirements of the SUSDP, (Australian Health Ministers' Advisory Council, 1997) which is a legal requirement under State and Territory legislation.


Recommendation 12:


It is recommended that suppliers review their labels as a matter of urgency and comply with the requirements of SUSDP:

Safety directions
SD1 Avoid contact with eyes

SD4 Avoid contact with skin

SD5 Wear protective gloves when mixing or using

SD8 Avoid breathing dust (or) vapour (or) spray mist

SD9 Use only in well ventilated area

WS12 Vapour is harmful to health on prolonged exposure


First aid instructions
If poisoning occurs contact a doctor or Poisons Information Centre.

If swallowed do not induce vomiting. Give a glass of water.

Avoid giving milk or oils.

Avoid giving alcohol.

If skin contact occurs, remove contaminated clothing and wash skin thoroughly.

Remove from contaminated area. Apply artificial respiration if not breathing.

If in eyes, hold eyes open, flood with water for at least 15 mins and see a doctor.

In addition other elements that are required to be on the label are:

the signal word POISON;

phrases KEEP OUT OF REACH OF CHILDREN; NOT TO BE TAKEN; and

percentage of trichloroethylene in the product.

Industrial Products

Substances used industrially need to comply with the requirements of the NOHSC National Code of Practice for the Labelling of Workplace Substances (National Occupational Health and Safety Commission (NOHSC), 1994).


Recommendation13:


It is therefore recommended that, where necessary, labels of industrial products be amended to include:

risk phrases

safety phrases

emergency procedures;

details of the amount of trichloroethylene present (exact amount or ranges); and

reference to MSDS.

Products or mixtures containing 0.1% or more of trichloroethylene should be classified as hazardous and labelled in accordance with the Labelling Code.
