Q
  • formerly known as the Material Safety Data Sheet (MSDS)
  • provided by the manufacturer, distributor, or importer of a chemical to provide information about the substance and its use
  • required to present the information in a uniform manner

- provides standard language or “building blocks” for communi
cating the hazards of chemicals in the SDS, just as on chemical labels. These “building
blocks” include the use of specific signal words, pictograms, hazard statements, and
precautionary statements.

48
Q

Specifies the maximum amount or concentration of a chemical to which a worker may be exposed. It can be established in one of two ways:
1. __________: At no time should this exposure limit be
exceeded .
2. _________: An average value
of exposure over the course of an 8-hour work shift

A

toxic

58
Q

The adverse effects of a substance resulting from a single exposure or multiple exposures over a very short time span (less than 24 hours).

Acute toxicity is usually determined by exposing animals to a given chemical to determine the lethal dose, 50% (LD50).

This is an experimental measure determined by administering varied doses of a chemical by some route to animals, observing the percentage lethality at these doses, and extrapolating to estimate the dose that would kill 50% of the animals.
