HAZARD SUMMARY
|
|
* Calcium Phosphide can affect you when breathed in.
|
|
* Phosphine gas is a highly toxic gas released when Calcium
|
|
Phosphide is wet or has contacted moisture. Consult the NJ DOH
|
|
Hazardous Substance Fact Sheet on Phosphine. * Calcium Phosphide
|
|
is a DANGEROUS FIRE and EXPLOSION HAZARD.
|
|
|
|
|
|
IDENTIFICATION
|
|
Calcium Phosphide is a reddish-brown crystalline (sugar or sand-
|
|
like) or a grey granular solid. It is used to kill rodents and
|
|
in explosives and fireworks.
|
|
|
|
REASON FOR CITATION
|
|
* Calcium Phosphide is on the Hazardous Substance List because it
|
|
is cited by DOT.
|
|
|
|
|
|
HOW TO DETERMINE IF YOU ARE BEING EXPOSED
|
|
* Exposure to hazardous substances should be routinely evaluated.
|
|
This may include collecting personal and area air samples. You
|
|
can obtain copies of sampling results from your employer. You
|
|
have a legal right to this information under OSHA 1910.20. * If
|
|
you think you are experiencing any work-related health problems,
|
|
see a doctor trained to recognize occupational diseases. Take
|
|
this Fact Sheet with you.
|
|
|
|
|
|
WORKPLACE EXPOSURE LIMITS
|
|
No occupational exposure limits have been established for Calcium
|
|
Phosphide. This does not mean that this substance is not
|
|
harmful. Safe work practices should always be followed.
|
|
|
|
|
|
WAYS OF REDUCING EXPOSURE
|
|
* Where possible, enclose operations and use local exhaust
|
|
ventilation at the site of chemical release. If local exhaust
|
|
ventilation or enclosure is not used, respirators should be worn.
|
|
* Wear protective work clothing.
|
|
* Dry brush or vacuum material thoroughly from skin immediately
|
|
after exposure to Calcium Phosphide and follow with large amounts
|
|
of water. * Post hazard and warning information in the work area.
|
|
In addition, as part of an ongoing education and training effort,
|
|
communicate all information on the health and safety hazards of
|
|
Calcium Phosphide to potentially exposed workers.
|
|
|
|
|
|
HEALTH HAZARD INFORMATION
|
|
|
|
Acute Health Effects
|
|
The following acute (short-term) health effects may occur
|
|
immediately or shortly after exposure to Calcium Phosphide:
|
|
|
|
* Exposure to Calcium Phosphide that has contacted moisture can
|
|
expose you to Phosphine gas which is highly toxic and dangerous.
|
|
consult the NJ DOH Hazardous Substance Fact Sheet on phosphine.
|
|
|
|
Chronic Health Effects
|
|
The following chronic (long-term) health effects can occur at
|
|
some time after exposure to Calcium Phosphide and can last for
|
|
months or years:
|
|
|
|
Cancer Hazard
|
|
* According to the information presently available to the New
|
|
Jersey Department of Health, Calcium Phosphide has not been
|
|
tested for its ability to cause cancer in animals.
|
|
|
|
Reproductive Hazard
|
|
* According to the information presently available to the New
|
|
Jersey Department of Health, Calcium Phosphide has not been
|
|
tested for its ability to adversely affect reproduction.
|
|
|
|
Other Long-Term Effects
|
|
* No chronic (long-term) health effects are known at this time.
|
|
|
|
|
|
MEDICAL
|
|
|
|
Medical Testing
|
|
There is no special test for this chemical. However, if illness
|
|
occurs or overexposure is suspected, medical attention is
|
|
recommended.
|
|
|
|
Any evaluation should include a careful history of past and
|
|
present symptoms with an exam. Medical tests that look for
|
|
damage already done are not a substitute for controlling
|
|
exposure.
|
|
|
|
Request copies of your medical testing. You have a legal right
|
|
to this information under OSHA 1910.20.
|
|
|
|
|
|
WORKPLACE CONTROLS AND PRACTICES
|
|
|
|
Unless a less toxic chemical can be substituted for a hazardous
|
|
substance, ENGINEERING CONTROLS are the most effective way of
|
|
reducing exposure. The best protection is to enclose operations
|
|
and/or provide local exhaust ventilation at the site of chemical
|
|
release. Isolating operations can also reduce exposure. Using
|
|
respirators or protective equipment is less effective than the
|
|
controls mentioned above, but is sometimes necessary.
|
|
|
|
In evaluating the controls present in your workplace, consider:
|
|
(1) how hazardous the substance is, (2) how much of the substance
|
|
is released into the workplace and (3) whether harmful skin or
|
|
eye contact could occur. Special controls should be in place for
|
|
highly toxic chemicals or when significant skin, eye, or
|
|
breathing exposures are possible.
|
|
|
|
Good WORK PRACTICES can help to reduce hazardous exposures. The
|
|
following work practices are recommended:
|
|
|
|
* Workers whose clothing has been contaminated by Calcium
|
|
Phosphide should change into clean clothing promptly. *
|
|
Contaminated work clothes should be laundered by individuals who
|
|
have been informed of the hazards of exposure to Calcium
|
|
Phosphide. * On skin contact with Calcium Phosphide, immediately
|
|
wash or shower to remove the chemical. At the end of the
|
|
workshift, wash any areas of the body that may have contacted
|
|
Calcium Phosphide, whether or not known skin contact has
|
|
occurred. * Do not eat, smoke, or drink where Calcium Phosphide
|
|
is handled, processed, or stored, since the chemical can be
|
|
swallowed. Wash hands carefully before eating or smoking. * Use
|
|
a vacuum to reduce dust during clean-up. Do not dry sweep.
|
|
|
|
FIRE HAZARDS
|
|
|
|
* Calcium Phosphide releases highly flammable Phosphine gas on
|
|
contact with moisture. * DO NOT USE WATER OR FOAM EXTINGUISHERS.
|
|
* Use dry chemical, soda ash, or lime extinguishers.
|
|
* If employees are expected to fight fires, they must be trained
|
|
and equipped as stated in OSHA 1910.156.
|
|
|
|
|
|
SPILLS AND EMERGENCIES
|
|
|
|
If Calcium Phosphide is spilled, take the following steps:
|
|
|
|
* Restrict persons not wearing protective equipment from area of
|
|
spill until clean-up is complete. * Remove all ignition sources.
|
|
* Ventilate area of spill.
|
|
* Collect powdered material in the most convenient and safe
|
|
manner and deposit in sealed containers. * It may be necessary to
|
|
contain and dispose of Calcium Phosphide as a HAZARDOUS WASTE.
|
|
Contact your state Department of Environmental Protection (DEP)
|
|
or your regional office of the federal Environmental Protection
|
|
Agency (EPA) for specific recommendations.
|
|
|
|
|
|
HANDLING AND STORAGE
|
|
|
|
* Prior to working with Calcium Phosphide you should be trained
|
|
on its proper handling and storage. * Store in tightly closed
|
|
containers in a cool, well-ventilated area away from STRONG
|
|
OXIDIZERS (such as CHLORINE, BROMINE and FLUORINE), STRONG ACIDS
|
|
(such as HYDROCHLORIC, SULFURIC and NITRIC), OXYGEN, SULFUR or
|
|
MOISTURE since violent reactions occur. * Sources of ignition,
|
|
such as smoking and open flames, are prohibited where Calcium
|
|
Phosphide is handled, used, or stored. * Use only nonsparking
|
|
tools and equipment, especially when opening and closing
|
|
containers of Calcium Phosphide. * Wherever Calcium Phosphide is
|
|
used, handled, manufactured, or stored, use explosion-proof
|
|
electrical equipment and fittings. * Do not store large amounts
|
|
of this material in a room protected by WATER sprinkler systems.
|
|
* Protect containers against physical damage.
|
|
|
|
|
|
FIRST AID
|
|
|
|
Eye Contact
|
|
* Immediately flush with large amounts of water, after quickly
|
|
wiping excess Calcium Phosphide from face with dry cloth.
|
|
Continue without stopping for at least 30 minutes, occasionally
|
|
lifting upper and lower lids. Seek medical attention immediately.
|
|
|
|
Skin Contact
|
|
* Remove contaminated clothing. Remove Calcium Phosphide from
|
|
skin with a dry cloth. Wash with soap and water, rinsing with
|
|
large amounts of water.
|
|
|
|
Breathing
|
|
* Remove the person from exposure.
|
|
* Begin rescue breathing if breathing has stopped and CPR if
|
|
heart action has stopped. * Transfer promptly to a medical
|
|
facility.
