Emergency overview
CAUSES RESPIRATORY TRACT AND EYE BURNS. FLAMMABLE GAS. GAS MAY
CAUSE FLASH FIRE. HIGH PRESSURE GAS. MAY BE HARMFUL IF INHALED.
CAN CAUSE TARGET ORGAN DAMAGE.
Keep away from sources of ignition. Keep away from heat (<52癈/125癋). Use only with
adequate ventilation. Extremely hazardous gas/liquid under pressure. Keep cylinder
valve closed when the product is not used. Gas may accumulate in confined areas.
: Dermal contact. Eye contact. Inhalation.
Routes of entry
Potential acute health effects
Corrosive to the respiratory system. May be harmful by inhalation.
Inhalation :
Corrosive to skin on contact.

Dimethylamine 124-40-3 > 99
This material is classified hazardous under the WHMIS Controlled Product Regulation in Canada.
See Sections 8, 11, 14 and 15 for details.
Section 4. First aid measures
Prompt medical attention is mandatory in all cases of overexposure to this gas. Rescue personnel should wear a
self-contained breathing apparatus and be aware of extreme fire and explosion hazard.
: In case of inhalation, all persons, still conscious, must be brought far from the
Inhalation
contaminated area and allowed to breath fresh air. The short time taken for this
operation is essential. All unconscious persons must be carried outside from the
contaminated area and given cardiopulmonary resuscitation (CPR) with a supplementary
of oxygen. Others should be treated according to their symptoms and needs. Get
medical attention immediately.

any contact lenses. In case of contact, immediately flush eyes with plenty of water for at
least 20 minutes. Get medical attention immediately.

Ingestion
the preventive measures in case of inhalation.
: Effects of contact or inhalation may be delayed. Provide general supportive measures.
Notes to physician
Oxygen may be beneficial. The medical doctor must be warned that the person inhaled
a very toxic gas.
Section 5. Fire fighting measures
: Flammable.
Flammability of the product
: Decomposition products may include the following materials:
Products of combustion
carbon dioxide
carbon monoxide
nitrogen oxides
Fire hazards in the presence : Container explosion may occur under fire conditions or when heated.
of various substances
: Use an extinguishing agent suitable for the surrounding fire.
Fire-fighting media and
instructions
Gas may accumulate in low or confined areas or travel a considerable distance to a
source of ignition and flash back, causing fire or explosion.
: Fire-fighters should wear appropriate protective equipment and self-contained breathing

Section 6. Accidental release measures
: EVACUATE ALL PERSONNEL FROM AFFECTED AREA.
Personal precautions
Use appropriate protective equipment. If leak is in user's equipment, be certain to purge
piping with an inert gas prior to attempting repairs. If leak is on container or container
valve, contact the closest Air Liquide Canada location.
: Ensure emergency procedures to deal with accidental gas releases are in place to avoid

contamination of the environment. Inform the relevant authorities if the product has
caused environmental pollution (sewers, waterways, soil or air).
: Immediately contact emergency personnel. Stop leak if without risk. Use spark-proof
Methods for cleaning up
tools and explosion-proof equipment. Note: see section 1 for emergency contact
information and section 13 for waste disposal.
Section 7. Handling and storage
: Keep away from heat, sparks and flame. To avoid fire, eliminate ignition sources. Use
Handling
explosion-proof electrical equipment (ventilating, lighting and material handling). Valve
protection caps must remain in place unless cylinder is secured with valve outlet piped to
usage point. Do not drag, slide or roll cylinders. Use a suitable hand truck for cylinder
movement. Use a pressure regulator when connecting cylinder to lower pressure piping
or systems. Do not heat cylinder by any means to increase the discharge rate of product
from the cylinder. Use a check valve or trap in the discharge line to prevent hazardous
back flow to the cylinder. Do not tamper with (valve) safety device. Close valve after
each use and when empty.

: Protect cylinders from physical damage. Store in cool, dry, well-ventilated area of non
Storage
combustible construction away from heavily trafficked areas and emergency exits. Do
not allow the temperature where cylinders are stored to exceed 52癈/125癋. Cylinders
must be stored upright and firmly secured to prevent falling or being knocked over. Full
and empty cylinders should be segregated. Use a "first in - first out" inventory system to
prevent full cylinders being stored for excessive periods of time. Post "No Smoking or
Open Flames" signs in the storage or use area. There should be no source of ignition in
the storage or use area. Segregate from oxidizing materials.
Section 8. Exposure controls/personal protection
: Use only in well-ventilated areas. Ensure that eyewash stations and safety showers are

close to the workstation location.
Personal protection
: Respirator selection must be based on known or anticipated exposure levels, the
Respiratory
hazards of the product and the safe working limits of the selected respirator.
: Wear suitable gloves for the application.
Hands
: Splash goggles.
Eyes
: Wear appropriate personal protective suit. Fire retardant clothing may be required when

handling or using flammable products.
Metal cap, safety shoes are recommended when handling cylinders.
Static dissipative footwear is recommended when handling or using flammable products.
Some applications of this product may require additionnal or other specific protective clothings. Please consult
your supervisor.
Personal protection in case : Safety glasses, goggles or face shield. Impervious gloves. Full suit. Metal cap, safety
boots. Wear MSHA/NIOSH-approved self-contained breathing apparatus or equivalent
of a major leak
and full protective gear.
