Chem lab safety

What is all eye wear rated?

ANSI Z87.1, protects against hazards including impact and penetration

safety glasses

metal or plastic safety frames and impact resistant lenses, side protection required

chemical splash goggles

tight fitting and cover the eye, eye sockets, and facial area around the eye completely, provide protection from impact, dust, and splashes

dust goggles

tight-fitting and resist the passage of large particles into the goggles

fluid resistant shields

provides splash protection from biological materials but does not provide protection against chemicals or impact hazards, not complaint with Z87.1, think Dr. pimple popper

Face shield

extends from the eye to below the chin across the width of the head, providing protection against splashes or sprays, can be used for UV protection too

laser eyewear

must be used only at the wavelength and energy/power which intended

welding shield

protects eyes from burns caused by intense light and protects eyes/face from flying sparks and metal splatter

Required lab attire

department approved glasses, long pants, shirt with sleeves that covers entire upper torso, flat soled shoes that cover the entire foot, hair longer than should length tied back

how long you should rinse your eyes in eyewash station

15 minutes

NOs for wearing in lab

leggings, dangling jewelry, sandals

Health Hazard, carcinogen, mutagenicity, reproductive toxicity, respiratory sensitizer, target organ toxicity, aspiration toxicity

Flame, flammables, pyrophorics, self-heating, emits flammable gas, self-reactives, organic peroxides

Exclamation Mark, irritant (skin and eye), skin sensitizer, acute toxicity (harmful), narcotic effects, respiratory tract irritant, hazardous to ozone layer

Gas Cylinder, Gases under pressure

Corrosion, skin corrosion/burns, eye damage, corrosive metals

Exploding Bomb, explosives, self-reactives, organic peroxides

Flame Over Circle, oxidizers

Environment, aquatic toxicity

Skull and Crossbones, acute toxicity (fatal or toxic)

toxicity information

Magnesium is flammable

TRUE

magnesium reacts with water and acid solutions

TRUE

hydrogen gas is considered and asphyxiant

TRUE

hydrogen gas is considered flammable

TRUE

A pyrophoric liquid freezes spontaneously and can pose a hazard as a result

FALSE

carcinogenity is a mechanical hazard

FALSE

NFPA

National Fire Protection Association

0 NFPA

No hazard, will not burn, stable

BLUE NFPA

Health hazard

RED NFPA

flammability hazard

YELLOW NFPA

instability hazard

WHITE NFPA

special hazard

1 NFPA

Blue, health: can cause significant irritation

red, flammability: must be preheated before ignition can occur

yellow, instability: normally stable, high temperatures make unstable

2 NFPA

Blue, health: can cause temporary incapacitation or residual injury

red, flammability: must be heated or high ambient temperature to burn

yellow, instability: violent chemical change at high temperatures or pressures

3 NFPA

blue, health: can cause serious or permanent injury

red, flammability: can be ignited under almost all ambient temperatures

yellow, instability: may explode at high temperature or shock

4 NFPA

blue. health: can be lethal

red, flammability: will vaporize and readily burn at normal temperatures

yellow, instability: may explode at normal temperatures and pressures

OX NFPA

Oxidizing

SA NFPA

Simple Asphyxiants

W NFPA

Reacts violently or explosively with water

cryogenic

being or related to very low temperature

GHS

Globally harmonized system of classification and labelling

GHS hazards

health hazards

physical hazards

environmental hazards

Asphyxiant

can result in suffocation

Teratogen

can cause birth defects

carcinogen

can cause cancer

mutagen

can cause genetic mutations

corrosive

can cause damage to living tissue

lachrymator

a substance that irritates the eyes and causes tears to flow

pyrophoric

liable to ignite spontaneously on exposure to aire

sensitizer

a substance that, after initial exposure, triggers an immune response, causing a person to develop an allergy

what is needed for a fire to start

fuel source, heat or ignition source, oxygen or other oxidizer, a chemical chain reaction

ABC Fire extinguishers can put out

Ordinary combustibles (paper cardboard plastics and rubber), Flammable and combustible liquids and gases (gasoline alcohols common organic solvents), Electrical equipment (hot plates stirrers ovens computers) NOT combustive water-reactive metals such as lithium sodium and potassium

Fire extinguishers that can put out fires from flammable organic solvents

ABC & CO2

Class A fires

ordinary combustibles (wood and paper)

Class B fires

flammable liquids like gasoline and oil

Class C fires

energized electrical equipment

Class D fires

involves combustible water-reactive metals such as lithium potassium and sodium and flammable metals such as magnesium
