Electrical Shock. Electrical shock accidents frequently result from contact with a "live" wire and
occasionally occur when a person is struck by lightning. Electrical shock is defined as a sudden
disruption of certain body functions as a result of an electric current flowing through the body between
two points. If a person has come in contact with an electric current, take the following steps:
- Turn off the switch if it is nearby, but do not waste time looking for it. Instead use a dry wooden pole,
dry clothing, dry rope, or some other material which will not conduct electricity to remove the person
from the wire. If a pole is not handy, simply drag the soldier off the wire by means of a loop of dry
rope or cloth. Do not touch the wire, apparatus, or soldier with your bare hands, or you will also get a
- Administer artificial respiration immediately after freeing the person from the wire or apparatus, as
electric shock causes breathing to cease. Also check the soldier's pulse, since electric shock may
cause his heart to stop. If you do not feel a pulse immediately, administer cardiopulmonary
Electrical Burns. Usually electrical shock is complicated by the simultaneous incidence of internal and/or
external burns. Considerable damage can occur to tissues, nerves, and muscles simply from the heat
generated by the passage of the electric current. Where internal tissues are destroyed, hemorrhaging
can occur, still further complicating the traumatic effects. External burns can also occur by contact with
the electrical source, which may be hot.
PART B - HAZARDOUS COMMUNICATION PROCEDURES
As Supervisor of the petroleum laboratory you will be expected to obtain and maintain Material Safety Data
Sheets (MSDS) and Hazardous Material Information System (HMIS) information when available, for all
hazardous substances used and stored in the laboratory.
MSDS and HMIS Emergency Response Procedures. Ensure that fire prevention and safety
SOP contain the MSDS and HMIS location for each hazardous substance used in the laboratory, for
reference in case of emergency. These documents should be kept in an easily accessible and central
location. The following types of information can be found in these sheets:
Psychological and Health Effects.
Emergency First-Aid Procedures.
Ingredients / Identity Information.
Special Protective Information.
Physical / Chemical Characteristics.
Fire and Explosion Hazard Data.
Health Hazard Data.
Precautions for Safe Handling and Use.
Additional Health Data.
PART C - SAFE HANDLING OF HAZARDOUS WASTE/MATERIAL
Handling Chemicals. To prevent personal injury and damage to surrounding areas while handling
chemicals, the following measures should be employed:
Always pour acid into water, especially sulfuric acid. Never pour water into acid.
Use Pyrex glassware when diluting acids. Ordinary glassware may be broken by the heat generated
from the mixture of acid and water.
Never heat mercury in an open container and never shake more than 20 millimeters of mercury in a
glass container. If a spill occurs, ensure adequate ventilation.
Hold the container cap in your hand when pouring a sample from a container or bottle.
Never place the cap or stopper on a counter, as it may contaminate the sample. Clean up the mercury
and sulfur together and put them in a suitable container for disposal IAW local environmental
If any chemical is spilled or splashed on the body, immediately wash the contaminated area thoroughly
