4. Make sure that all containers are properly

labeled. Never fill a container with material other than that in-

dicated on the label.

Keep bottles of acid or alkalis on low shelves

(e) Bases.

Use a pyrex or equivalent container when diluting

bases, the heat generated when making base solutions

may break ordinary glassware. Pour the base into the

water. Never use cracked or broken glassware for any

purpose. Always wear goggles when preparing and han-

dling base solutions. If bases come in contact with

the skin or eyes, rinse immediately with large amounts

of water for at least 15 minutes and seek medical at-

tention particular for base splashes involving the

eyes. Under no circumstances should any acid solu-

tion be applied to the area where the base contacted.

(f) Caps (or Stoppers).

Hold the cap in the hand when pouring a sample from

a container; never place it on a bench or worktable

where it could become contaminated. Be sure to

return the cap to the contaner from which it was

removed. Hold the cap of a reagent bottle between

the fingers of the pouring hand when pouring from

the bottle; never lay it on a surface that might be

touched by personnel or their clothing.

Keep acid and caustic bottles tightly stoppered.

Flush and dry the outside of the bottles before

returning them to the reagent shelf. Wipe up any

spills.

(g) Excess Chemicals or Reagents.

Never return excess chemicals, reagents, or samples

to the original container. Similarly, do not place

spatulas or other objects in reagent containers for

any reason.

(h) Gas Cylinders.
