GENERAL CONCEPTS OF TOXICOLOGY

HOW WELL THE BODY ACCEPTS A SUBSTANCE DEPENDS ON:

THE TYPE OF SUBSTANCE

THE AMOUNT (DOSE) ABSORBED

THE PERIOD OF TIME OVER WHICH IT IS ABSORBED

THE SUSCEPTIBILITY/SENSITIVITY OF THE PERSON EXPOSED

EVERYTHING IS TOXIC; IT ALL DEPENDS ON THE DOSE


H - 8

GENERAL CONCEPTS OF TOXICOLOGY

DEGREE OF HARM TO BODY DEPENDENT ON:

CONDITIONS OF USE

PHYSICAL PROPERTIES OF THE CHEMICAL

ROUTES OF EXPOSURE

DURATION OF THE EXPOSURE

CONCENTRATION OF THE CONTAMINANT IN AIR

INDIVIDUAL SUSCEPTIBILITY OF THE EXPOSED PERSON

TOXICITY OF THE CHEMICAL

GASES - PRE-OPERATION SAFETY

1. Inspect cylinder for damage before use.

2. Ensure “in use” label is present.

3. Ensure all labels and warnings are readable.

4. Place upright on stable dry surface.

5. Ensure cylinder is restrained above mid-point.

6. Keep heat, flame, and electricity away from cylinder.

7. Operate in accordance with local safety procedures.

HANDLING GASES


H - 15

GASES - POST-OPERATION SAFETY

1. Ensure “empty” or like label present.

2. Remove from operation following procedures.

3. Ensure valve closed completely and cap cylinder.

4. Never roll, transport cylinders using handtruck.

5. Never underestimate hazards associated with compressed gases.

HANDLING GASES


H - 16

GASES - STORAGE REQUIREMENTS

Store only in designated areas.

Store and use on a first-in, first-out basis.

Never store without proper labeling.

Identify all empty cylinders.

Store like gases with like gases.

Separate empty cylinders from full ones.

Store within proper temperature ranges.

STORING GASES


H - 17

GASES - STORAGE REQUIREMENTS

TOTES, DRUMS AND BARRELS

Should be moved to storage ASAP Make best use of just-in-time system Bonding wires must be used Local fire codes must be considered Bonding - container to container Grounding - container to structural ground No ignition sources within 25 feet


FLAMMABLELIQUIDS


H - 24

PORTABLE CONTAINERS

Bond from drum to container during transfer Store in safety cabinets when not in use Check for leak-tightness Check for serviceable vent mechanism Do not remove flame arrester screens Do not overfill (high temps will cause overflow) Follow warnings and safety procedures

HANDLING CORROSIVE LIQUIDS

AFFECT OTHER MATERIALS BY CONTACT:

Acids and bases affect material by contact Acids and bases affect each other Oxidizers increase hazard during fires

ACIDS BASES OXIDIZERS


H - 27

A material such as a chlorate, permanganate, or inorganic peroxide that will give off oxygen readily to stimulate the combustion of organic material.


OXIDIZER

DOT DEFINITION

ACIDS AND BASES

- pH. THE pH OF A LIQUID IS THE NUMERICAL MEASUREOF ITS RELATIVE ACIDITY OR ALKALINITY. THE RANGEIS FROM 0 - 14 WITH A NEUTRAL LEVEL EXPRESSED ASA pH OF 7.0.

ABOVE 7.0 THE LIQUID IS MORE ALKALINE OR BASIC.

BELOW 7.0 THE LIQUID IS MORE ACIDIC.
