3. HAZARD IDENTIFICATION
EMERGENCY OVERVIEW: This gas mixture is a colorless gas which is odorless. The Phosphine component of this gas mixture is an
extremely toxic gas; even brief over-exposures to relatively low doses may have significant health consequences. Effects of an acute overexposure include central nervous system disorders (i.e. headaches, tremors), lung problems, abdominal pains, effects on the heart.
Additionally, releases of this gas mixture may produce oxygen-deficient atmospheres (especially in confined spaces or other poorly-ventilated
environments); individuals in such atmospheres may be asphyxiated.
SYMPTOMS OF OVER-EXPOSURE BY ROUTE OF EXPOSURE: The most significant route
HAZARDO US M ATER IAL IDENTIFICATIO N SYS TEM
of over-exposure for this gas mixture is by inhalation.
INHALATION: Due to the small size of an individual cylinder of this gas mixture, no unusual

3. HAZARD IDENTIFICATION (Continued)
ACUTE: Due to the small size of the individual cylinder of this gas mixture, no unusual health effects from exposure to the product are anticipated
under routine circumstances of use. Phosphine (a component of this gas mixture) is an extremely toxic gas; even brief over-exposures to relatively
low doses may have significant health consequences. Effects of an acute over-exposure include central nervous system disorders (i.e. headaches,
tremors), lung problems, abdominal pains, effects on the heart. Contact with the skin or eyes with Phosphine in the presence of moisture can
cause irritation, due to the formation of phosphoric acid.
CHRONIC: Effects of chronic low level exposures to the Phosphine component of this gas mixture may result in anemia, bronchitis, gastrointestinal
disorders, and visual, speech, and motor disturbances. Refer to Section 11 (Toxicology Information) for additional data. Chronic exposure to
oxygen-deficient atmospheres (below 18% oxygen in air) may affect the heart and nervous system.
TARGET ORGANS: ACUTE: Respiratory system, central nervous system, cardiac system, skin, eyes. CHRONIC: Blood system, respiratory
system, gastrointestinal system, cardiac system, central nervous system.
4. FIRST-AID MEASURES
RESCUERS SHOULD NOT ATTEMPT TO RETRIEVE VICTIMS OF EXPOSURE TO THIS GAS MIXTURE WITHOUT ADEQUATE PERSONAL
PROTECTIVE EQUIPMENT. At a minimum, Self-Contained Breathing Apparatus must be worn.
No unusual health effects are anticipated after exposure to this gas mixture, due to the small cylinder size. If any adverse symptom develops after
over-exposure to this gas mixture, remove victim(s) to fresh air as quickly as possible. Only trained personnel should administer supplemental
oxygen and/or cardio-pulmonary resuscitation if necessary. Victim(s) who experience any adverse effect after over-exposure to this gas mixture
must be taken for medical attention. Rescuers should be taken for medical attention if necessary. Take a copy of the label and the MSDS to
physician or other health professional with victim(s).
SKIN EXPOSURE: If irritation of the skin develops after exposure to this gas mixture, immediately begin decontamination with running water.
Minimum flushing is for 15 minutes. Remove exposed or contaminated clothing, taking care not to contaminate eyes. Victim must seek immediate
medical attention.
EYE EXPOSURE: If irritation of the eye develops after exposure to this gas mixture, open victim's eyes while under gentle running water. Use
sufficient force to open eyelids. Have victim "roll" eyes. Minimum flushing is for 15 minutes. Seek medical assistance immediately, preferably an
ophthalmologist.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: Any respiratory disorder, heart condition, or central nervous system condition, may be
aggravated by over-exposure to Phosphine. Additionally, skin and eye conditions may be aggravated by Phosphine exposures.
RECOMMENDATIONS TO PHYSICIANS: Administer oxygen. Victims of exposure to Phosgene must be monitored closely for delayed pulmonary
edema. There is no specific antidote to Phosphine poisoning; therefore, treatment is symptomatic and supportive.

6. ACCIDENTAL RELEASE MEASURES
LEAK RESPONSE: Due to the small size and content of the cylinder, an accidental release of this gas mixture presents significantly less risk of
over-exposure to Phosphine, an oxygen-deficient environment, and other safety hazards than a similar release from a larger cylinder. However, as
with any chemical release, extreme caution must be used during emergency response procedures. In the event of a release in which the
atmosphere is unknown, and in which other chemicals are potentially involved, evacuate immediate area. Such releases should be responded to
by trained personnel using pre-planned procedures. Proper protective equipment should be used. In case of a leak, clear the affected area,
protect people, and respond with trained personnel. Allow the gas mixture to dissipate. If necessary, monitor the surrounding area (and the original
area of the release) for oxygen. A colorimetric tube is available for Phosphine. The level of Phosphine must be at acceptable levels (less than
50% of the TLV; TLV = 0.3 ppm) and Oxygen levels must be above 19.5% before non-emergency personnel are allowed to re-enter area.
If leaking incidentally from the cylinder, contact your supplier.
7. HANDLING and USE
WORK PRACTICES AND HYGIENE PRACTICES: Be observant for the odor of sulfur; this odor is indicative of a potential over-exposure the
Sulfur Dioxide of this gas mixture. Do not attempt to repair, adjust, or in any other way modify cylinders containing this gas mixture. If there is a
malfunction or another type of operational problem, contact the nearest distributor immediately. Eye wash stations/safety showers should be near
areas where this gas mixture is used or stored. All work operations should be monitored in such a way that emergency personnel can be
immediately contacted in the event of a release. All work practices should minimize releases of Sulfur Dioxide and Nitrogen Monoxide-containing
gas mixtures.
STORAGE AND HANDLING PRACTICES: Cylinders should be firmly secured to prevent falling or being knocked-over. Cylinders must be
protected from the environment, and preferably kept at room temperature (approximately 21°C [70°F]). Cylinders should be stored in dry, wellventilated areas, away from sources of heat, ignition, and direct sunlight. Protect cylinders against physical damage. Full and empty cylinders
should be segregated. Use a first-in, first-out inventory system to prevent full containers from being stored for long periods of time. These cylinders
are not refillable. WARNING! Do not refill DOT 39 cylinders. To do so may cause personal injury or property damage.
SPECIAL PRECAUTIONS FOR HANDLING GAS CYLINDERS: WARNING! Compressed gases can present significant safety hazards. During
cylinder use, use equipment designed for these specific cylinders. Ensure all lines and equipment are rated for proper service pressure.
PROTECTIVE PRACTICES DURING MAINTENANCE OF CONTAMINATED EQUIPMENT: Follow practices indicated in Section 6 (Accidental
Release Measures). Make certain that application equipment is locked and tagged-out safely. Always use product in areas where adequate
ventilation is provided.
8. EXPOSURE CONTROLS - PERSONAL PROTECTION
VENTILATION AND ENGINEERING CONTROLS: No special ventilation systems or engineering controls are needed under normal
circumstances of use. As with all chemicals, use this gas mixture in well-ventilated areas. If this gas mixture is used in a poorly-ventilated area,
install automatic monitoring equipment to detect the levels of Phosphine and Oxygen.
RESPIRATORY PROTECTION: No special respiratory protection is required under normal circumstances of use. Maintain Phosphine levels below
50% of the TLV (TLV = 0.3 ppm) and oxygen levels above 19.5% in the workplace. Use supplied air respiratory protection when Phosphine levels
exceed 50% of the TLV (TLV = 0.3 ppm), oxygen levels are below 19.5%, or during emergency response to a release of this gas mixture. During
an emergency situation, before entering the area, check the concentration of Phosphine and Oxygen. If respiratory protection is required, follow the

16. OTHER INFORMATION
INFORMATION ABOUT DOT-39 NRC (Non-Refillable Cylinder) PRODUCTS
DOT 39 cylinders ship as hazardous materials when full. Once the cylinders are relieved of pressure (empty) they are not considered
hazardous material or waste. Residual gas in this type of cylinder is not an issue because toxic gas mixtures are prohibited. Calibration gas
mixtures typically packaged in these cylinders are Nonflammable n.o.s., UN 1956. A small percentage of calibration gases packaged in DOT
39 cylinders are flammable or oxidizing gas mixtures.
For disposal of used DOT-39 cylinders, it is acceptable to place them in a landfill if local laws permit. Their disposal is no different than that
employed with other DOT containers such as spray paint cans, household aerosols, or disposable cylinders of propane (for camping, torch
etc.). When feasible, we recommended recycling for scrap metal content. CALGAZ will do this for any customer that wishes to return
cylinders to us prepaid. All that is required is a phone call to make arrangements so we may anticipate arrival. Scrapping cylinders involves
some preparation before the metal dealer may accept them. We perform this operation as a service to valued customers who want to
participate.
MIXTURES: When two or more gases or liquefied gases are mixed, their hazardous properties may combine to create additional, unexpected
hazards. Obtain and evaluate the safety information for each component before you produce the mixture. Consult an Industrial Hygienist or
other trained person when you make your safety evaluation of the end product. Remember, gases and liquids have properties which can
