Definition: LD50

LD50 (Lethal Dose50) is the amount of a

substance that, when administered by

a defined route of entry (e.g. oral or

dermal) over a specified period of

time, is expected to cause the death of

50 per cent of a defined animalpopulation.


8/24

Definition: LC50

LC50 (Lethal Concentration50) is the

amount of a substance in air that,

when given by inhalation over a

specified period of time, is expected to

cause the death in 50 per cent of a

defined animal population.

When a Spill Strikes

1)Assess the risk

Minor Spill, handled by personnel within lab or

department. Minor spills should be cleaned-up at the

time of the spill.

Major Spill, isolate area. Major spillsmay require special treatment, equipment or

emergency assistance.


22/24

When a Spill Strikes

2) Select personal protective equipment (PPE) such as rubbergloves and goggles.

consult MSDS and other literature sources3) Confine the spill

Limit the spill area by blocking, diverting, or confining spill

Use absorbents, tiger tails, drain plugs, dikes

4) Stop the Source

5) DecontaminateDecontaminate site, personnel, & equipment by removing orneutralizing the hazardous materials

6) Complete Incident Report


23/24

Additional Information

MSDSs Must be Readily Available

3 Year Expiry Date New Information becomes Available

You should receive one with each new chemical

You should review the MSDS before using any new

chemical.


24/24

MSDS Location

MSDSs are required to be accessible by you at all

times.

Dont necessarily have to be located in each lab

(although it is a good idea)

Ask your supervisor where they are located for your

area.
