3.0 Chemical Safety

The production and use of chemicals arefundamental factors in the economic developmentof all countries, whether they are industrializedor developing.In one way or another, chemicals affectdirectly or indirectly the lives of all humans and

are essential to our :feeding(fertilizers, pesticides, food additives,packing),our health (pharmaceuticals, cleaning materials),

our well being (appliances, fuels, etc).

Under OSHA, 1994 two regulationsused:

i. Classification, Packaging andLabeling hazardous chemicals, 1997

ii. Use and Standard of Exposure ofChemicals Hazardous to Health,2000

Chemical Safety Laws


6/83

SCETMICET


The first and most essential step leading to safeuse of chemicals are to know their:identity,

hazards to health and the environment andmeans to control them.

This inherently complex knowledge must be

organizedin such a way that information on thehazardsand corresponding protective measurescan be identified and conveyedto the user in aform that is easy to understand.

An essential tool for establishing an effectiveinformation transfer so that the degree ofthe chemical hazard represents for man and

to identify the hazardous properties ofchemicals which may constitute a risk during normalhandling or use, risks to health, property or theenvironment.

to be introduced to the hazards they presentto give the basic information, in a suitablemanner, such as using a properly made label.

All chemicals, both substances andpreparations, should have a clear marking toindicate their identity.

The packages and containers of dangeroussubstances and preparations should, in additionto marking only, to have a label with requiredinformation.

The label should draw attention to theinherent danger topersons handling or usingthe chemical.

Chemical Labeling

SCETMICET


Symbols and pictograms have been establishedfor each hazard category listed.

The symbol forms an integral part of the labeland gives an immediate idea of the types ofhazards that the substance or the preparation may

cause.To specify the type of danger pertinent standardrisk phrases should also be included in the label.

Advice on the precautions necessary in thehandling of chemicals are given with standardSafety phrases & Risk phrases also included inthe label.

information in Section 8.

Actions to take when

dealing with a spill.

Containment of spill:Stop leak if it can be done without

risk. Dike spill using absorbent or impervious materials

such as earth, sand or clay.

or other inert absorbent. Shovel up into an appropriate

closed container (see Section 7: Handling and Storage).

Decontaminate tools and equipment following cleanup.

Environmental and regulatory reporting:If spilled onthe ground, the affected area should be removed to a

depth of 12 inches and placed in an appropriate

container for disposal. Prevent material from entering

public sewer system or any waterways. Spills may be

reported to the National Response Center (800-424-

8802) and to state and/or local agencies.

goods can present the same hazards as thechemical substance or product they contained andshould also be regarded as dangerous goods.

Risk of spillageduring the transportof hazardous goods.

When incompatible substances mixwith each other there is a possibility of

a chemical reaction, which can produceenough heat to cause fire or explosionand can release dangerous gases.

Handling Chemicals - What aredangerous situations?

MICETp y

Spillage is possible in the following situations:

goods are not properly packaged;handling (loading, unloading, etc.) is donewithout reference to the contents (perhapsbecause of missing or incomplete labeling);fire; either when the load or the vehicle is

burning;road accident;defected tightness or incomplete closing of

valves and connections

Spillage



63/83

MICETp y

A risk of an accident is present whenVehicles carrying dangerous goods are leftto stand unattended;

the vehicle or container runs loose becauseit is not properly connected or secured;the load starts to move during transport;

spillage is not quickly washed away fromthe vehicles or containers;spillage is not properly cleaned.

Calcium carbide (used in the production of acetyleneand pyrotechnics) comes to contact with water, itreleases the extremely flammable gas of acetylene(also in welding flame) and creates an explosion

hazard.

Proper communication within the transport chain isthe basis for all other safety measures. Safetyactivities are targeted to:

point out practical problems concerningeither the workplace as a whole or individualtasks;

create a forum to discuss these problemsand to try to find solutions that improve thehealth of workers and reduce loss of

materials;

This should involve all parties in theworkplace. The task could be given to acommittee including representatives of

different parts of the transport company.

The committee could consider emergency

planning and safety education. Ideas fromboth workers and the employer should beencouraged and discussed.
