Halotron-1
(Fire Extinguishing Agent with Expellant)
Do not enter confined space unless adequately ventilated.
In case of inadequate ventilation wear respiratory protection.
Do not breathe fume/gas/mist/vapors/spray.
Wash hands thoroughly after handling.
Do not eat, drink or smoke when using this product.
Get medical advice/attention if you feel unwell.
If exposed or concerned: Call a poison center or doctor.
Keep container tightly closed.
Protect from sunlight and store in well-ventilated place.
Store locked up.
Dispose of contents/container is accordance with local and national regulations.
Direct contact with the cold gas or liquid can cause freezing of exposed tissues. Avoid direct inhalation of
undiluted gas. Can cause suffocation by reducing oxygen available for breathing. Breathing very high
concentrations can cause dizziness, shortness of breath, unconsciousness or asphyxiation.
Specific Concentration Limits
The values listed below represent the percentages of ingredients of unknown toxicity.

Note: The expellant is argon.
Description of necessary first-aid measures
Immediately flood the eye with plenty of warm water for at least 15 minutes, holding the eye open.
Obtain medical attention if soreness or redness persists.
Flush with water. Obtain medical attention if frostbite or blistering occurs or redness persists.

Halotron-1
(Fire Extinguishing Agent with Expellant)
Ingestion is not considered a potential route of exposure.
Remove from exposure. If there is difficulty in breathing, give oxygen. Obtain medical attention
immediately.
Most important symptoms/effects, acute and delayed
Aside from the information found under Description of necessary first aid measures (above) and
Indication of immediate medical attention and special treatment needed, no additional symptoms and
effects are anticipated.
Indication of immediate medical attention and special treatment needed
In case of frostbite, place the frostbitten part in warm water. If warm water is not available or impractical
to use, wrap the affected parts gently in blankets. DO NOT USE HOT WATER.
The use of catecholamines such as adrenaline, or similar compounds can increase susceptibility to heart
irregularities caused by excessive exposure to these types of compounds.
Suitable Extinguishing Media
Halotron-1 is used as an extinguishing agent and therefore is not a problem when trying to control a fire.
Use extinguishing agent appropriate to other materials involved. Keep containers and surroundings cool
with water spray as containers may rupture or burst in the heat of a fire. The concentrated agent when
applied to fire can produce toxic by-products specifically hydrogen halides which can cause damage.
Avoid inhalation of these materials by evacuating and ventilating the area.
Specific hazards arising from the chemical
Containers may explode in heat of fire.
Special Protective Actions for Fire-Fighters
Wear full protective clothing and self-contained breathing apparatus as appropriate for specific fire
conditions.
ACCIDENTAL RELEASE MEASURES
Personal precautions, protective equipment and emergency procedures
Remove leaking cylinder to a safe place. Ventilate the area. Vapors can accumulate in low areas.
Leaks inside confined spaces may cause suffocation as oxygen is displaced and should not be entered
without a self-contained breathing apparatus.
Manufacturer’s Recommended 1 Hr. Emergency Exposure Limit: 1000ppm (v/v)
Manufacturer’s Recommended 1 Min. Emergency Exposure Limit: 2500ppm (v/v)

(Fire Extinguishing Agent with Expellant)
Precautions for safe handling
Wear appropriate protective clothing. Prevent skin and eye contact.
Conditions for safe storage
Pressurized containers should be properly stored and secured to prevent falling or being knocked over.
Do not drag, slide or roll pressurized containers. Do not drop pressurized containers or permit them to
strike against each other. Never apply flame or localized heat directly to any part of the pressurized or
plastic container. Store pressurized containers away from high heat sources. Storage area should be: cool - dry - well ventilated - under cover - out of direct sunlight
EXPOSURE CONTROLS/PERSONAL PROTECTION
Control parameters
Exposure limits are listed below, if they exist.
Workplace Environmental Exposure Level (chronic handling)
WEEL(AIHA)(8 hrs): 50 ppm (v/v), based on the primary component
Manufacturer’s Recommended 1 Hr. Emergency Exposure Limit: 1000ppm (v/v)
Manufacturer’s Recommended 1 Min. Emergency Exposure Limit: 2500ppm (v/v)
Exposure Level When Using Halotron I in a Fire Extinguisher
Exposure when using this material as a fire extinguishing agent - the exposure should not exceed 20,000
ppm (v/v). Guidelines for the safe minimum volume when this agent is used in a confined space are
provided on the label of the extinguisher.
Appropriate engineering controls
Use with adequate ventilation. There should be local procedures for the selection, training, inspection
and maintenance of this equipment. When used in large volumes or odor becomes apparent, use local
exhaust ventilation.
Individual protection measures
Not normally required under conditions of use as a portable fire extinguisher. In oxygen deficient
atmospheres, use a self contained breathing apparatus, as an air purifying respirator will not provide
protection.
Neoprene, PVC or PVA gloves
Chemical goggles or safety glasses with side shields.
