HAZARD SYMBOLS

Substances with known hazards are labelled in accordance with UK Regulations and EEC Directives and show the Hazard symbol(s),

Substance Identification Number and phrases covering major Risk and Safety precautions.

Hazard symbols and Risk and Safety phrase numbers are also shown in the catalogue, Flash points closed cup unless marked OC

(open cup) and special Storage conditions being given where appropriate.

In addition, recommendations for First Aid, Fire, Spillage and Disposal treatment are shown in code form at the end of an items entry.

Explanation of the codes, hazard symbols, and general advice can be found on the following pages.

All the above information is available in the form of a Health and Safety Data Sheet which we will provide on request.

Substances which present a serious risk

of acute or chronic poisoning, by inhalation,

ingestion or skin absorption.

ToxicSubstances which present moderate risks

to health by inhalation, ingestion or skin

absorption.

HarmfulSubstances which are non-corrosive but are

liable to cause inflammation through

immediate prolonged or repeated contact

with the skin or mucous membranes.

IrritantSubstances which, were they to enter into

the environment, would present or might

present an immediate or delayed danger

for one or more components of theenvironment.

Dangerousto theenvironment

Those items included in the Schedule 1 list

of The Poisons Rules 1978 are identified in

S.1.Poison

Substances which destroy living tissue.

CorrosiveSubstances which may explode under

the effect of flame or heat or which are

more sensitive to shock or friction than

dinitrobenzene.

Explosive

Extremely flammable liquids have a flash

point less than 0C and a boiling point less

than or equal to 35C.

Highly flammable substances include:

(a) Those which may become hot and

finally catch fire in contact with air at

ambient temperature without

application of energy.

(b) Those which may readily catch fire after

brief contact with a source of ignition

and which continue to burn or to be

consumed after removal of the source

of ignition.

(c) Those which are gaseous and

flammable in air at normal pressure.

(d) Those in contact with water or damp

air which evolve highly flammablegases in dangerous quantities.

(e) Liquids have a flash point below 21C.

Flammable liquids are those having a

flash point equal to or greater than 21C

and less than or equal to 55C.

FlammableSubstances which give rise to highlyexothermic reactions in contact with

other substances, particularly flammable

substances.
