Q

What are GHS explosives?

A

Explosive substance or mixture is solid or liquied which is in itself capable by chemical reaction of producing gas at such a temperature and pressure and at such a speed to cause damage to sorroundings

pyrotechnic substances are included even when they do not evolve gases

A

dsigned to produce an effect by heat, light, sound, gas or smoke or combination as result of non-detonative, self-sustaining exothermic chemical reactions

Q

What are flammable aerosols?

A

Aerosols are any gas compressed, liquified, or dissolved under pressure within a non-refillable container made of metal, glass or plastic with or without liquid, paste or powder

container fitted with release device allowing contents to be ejected as solid or liquid particles in suspension in a gas, as a foam, paste or powder or in a liquid or gaseous state

aerosols considered flammable if they contain any component classified as flammable according to GHS criteria for flammable liquids, flammable gases, flammable solids

Q

What are oxidizing gases?

A

any gas which may generally by providing oxygen, cause or contribute to the combustion of other material more than air does

by providing oxygen, they cause or contribute to combustion of other material

Q

What are flammable solids?

A

solids that are readily combustible, or may cause or contribute to fire through friction

readily combustible solids are powdereed, granular, or pasty wich are dangerous if they can be easily ignited by brief contact with ignition source and if flame spreads rapidly

Q

What are self-reactive substances?

A

Thermally unstable liquids, or solids liable to undergo a strongly exothermic thermal decomposition even without participation of oxygen (air)

excludes materials classified as explosive, organic peroxides or as oxidizing

Q

What are self-heating substances?

A

solid or liquid, other than a pyrophoric substance, which be reaction with air, and without energy supply, is liable to self-heat

differs from pyrophoric substance in that it will only ignite when in large amounts (kilograms) and after long periods of time (hours or days)

Q

What does substance which on contact with water emit flammable gases mean?

A

in contat with water, emit flammable gases are solids or liquids which by interaction with water are liable to become spontaneously flammable or give off flammable gases in dangerous quantities

17
Q

What are oxidizing liquids?

A

liquid which, while in itself is not necessarily combustible, may generally by yielding oxygen, cuase or contribute to combustion of other material

18
Q

What are oxidizing solids?

A

generally by yielding oxygen, cause or contribute to combustion of other material

not necessarily combustible by itself

19
Q

What are organic peroxides?

A

liquid or solid, which contains bivalent -O-O- structure and considered a derivative of hydrogen peroxide where one or both of the hydrogen atoms have been replaced by organic radicals

may be:

liable to explosive decomposition

burn rapidly

sensitive to impact or friction

react dangerously with other substances

20
Q

What are substances corrosive to metal?

A

substance or mixture that by chemical action will materially damage or even destroy metals

21
Q

List the 10 health hazard classifications by GHS

A

acute toxicity

skin corrosion/irritant

serious eye damage/eye irritant

respiratory or skin sensitization

germ cell mutagenicity

carcinogenicity

reproductive toxicology

target organ systemic toxicity- single exposure

target organ systemic toxicity- repeated exposure

aspiration toxicity

22
Q

What does skin corrosion health hazard mean?

A

production of irreversible damage to skin following application of test substance for up to 4 hours

23
Q

What does serious eye damage classification mean?

A

tissue damage in the eye, or serious physical decay of vision following application of test substance to front surface of eye which is NOT fully reversible within 21 days of application

24
Q

What does skin irritation hazard class mean?

A

production of REVERSIBLE damage to skin following application of test substance for up to 4 hours

25
Q

What does eye irritation mean?

A

changes in eye following applicaiton of test substance to front surface of eye, which are fully reversible within 21 days of application

26
Q

What is a respiratory sensitizer classification?

A

substance that induces hypersensitivity of the airways following inhalation

27
Q

What is a skin sensitizer classification?

A

substance will induce an allergic response following skin contact

28
Q

What does germ cell mutagenicity mean?

A

increased occurence of mutations in populations of cells and or organisms

29
Q

What does carcinogenicity mean?

A

chemical substance or mixture of chemical substances which induce cancer or increase incidence

30
Q

What does reproductive toxicity mean?

A

adverse effects on sexual function and fertility in adult males and females

developmental toxicity in offspring

31
Q

What is target organ systemic toxicity (TOST) single exposure & repeated exposure?

A

all significant health effects not otherwise specifically included in GHS that can impair function, both reversible and irreversible, immediate or delayed are included in the non-lethal target organ/sysemic toxiity class (TOST)

narcotic effects and respiratory tract irritation are considered to be target organ systemic effects following a single exposure

32
Q

What is an aspiration hazard?

A

servere acute effects such as chemical pneumonia, varying degrees of pulmonary injury or death following aspiration

aspiration is entry of liquid or solid directly through the oral or nasal cavity, or indirectly from vomitting into the trachea and lower respiratory system

33
Q

What is acute aquatic toxicity?

A

cause injury to an aquatic organism in short-term exposure

34
Q

What is chronic aquatic toxicity?

A

potential or actual properties of a material cause adverse effects to aquatic organisms during exposures that are determined in relation to the lifecycle of the organism
