The document outlines waste disposal procedures in a laboratory setting, emphasizing the proper disposal of paper, wood, glass, and chemical wastes. It specifies the handling of acid solutions, toxic chemicals, and the need for careful transportation of corrosives. Urgent actions are recommended for spills, with specific methods for both solids and liquids to ensure safety and prevent hazards.

1. WASTE DISPOSAL PROCEDURES
Laboratory in Chem

2. Deposit pieces of
paper, wood, glass,
and other wastes in
the garbage can.

3. Deposit waste acid solutions into
the acid jar. Any other toxic
chemical must be disposed of in
the waste can (if solid) or in the
sink, followed by large
quantities of water (if liquid).

4. Be very careful in pouring
and transporting acids and
other corrosive chemicals.
Acids may be transported
only if the container is
properly capped.

5. Spilled solids should be placed in
appropriate solid waste container
and should be done promptly
because many solids are
hydroscopic and become difficult
to sweep up in a short time as in
the case of NaOH and KOH.

6. Spilled acids, and
for bases, use
sodium bisulfate.

7. If the spilled material is
very volatile, clear the area
and let it evaporate.
Provide no chance of igniting
flammable compounds.
