If so,                Titanium will burn in nitrogen the main component of this product.  Pentane is incompatible with

Which ones?    strong oxidizers (i.e. chlorine, bromine pentafluoride, oxygen difluoride, and nitrogen trifluoride)

Reactivity and under what conditions

 

The components of this gas mixture do not decompose, per se, but can react with other compounds in the heat of a fire.  Cylinders exposed to high temperatures or direct flame can rupture.

 

 

 

Hazardous Decomposition Products

 

The thermal decomposition of products of pentane include carbon oxides.

SECTION VII– PREVENTIVE MEASURES

Personal Protective Equipment: 

 

Gloves (specify)

 N/A

Respiratory (specify):   Not required with normal use, only if

Pentane or CO exceeds levels in Section II

Eye (specify)

Safety glasses

Footwear (specify)

N/A

Clothing (specify)

N/A

Other (specify)

 

Engineering Controls (e.g., ventilation, enclosed process, specify):    No special ventilation systems or engineering controls are needed under normal circumstances of use.  As with all chemicals, use product in well ventilated areas.

Leak & Spill Procedure:  Due to the small size and content of the cylinder (e.g. 105 liters), an accidental release of this product presents significantly less risk of an oxygen deficient environment and other safety hazards than a similar release from a larger cylinder.

Waste Disposal:  Once the cylinders are relieved of pressure (empty) they are not considered hazardous material or waste.  It is acceptable to place empty cylinders in a landfill if local laws permit.

Handling Procedures & Equipment:  Cylinders should be firmly secured to prevent falling or being knocked-over. 

 

Storage Requirements: Cylinders must be protected from the environment, and preferably kept at room temperature.  Cylinders should be stored in dry, well ventilated areas, away from sources of heat, ignition, and direct sunlight.  Protect cylinders against physical damage.

Special Shipping Information:  This material is hazardous as defined by 49 CFR 172.101 by the U.S. Department of Transportation.  Shipping name: compressed gases, n.o.s. (Nitrogen, Oxygen).  Hazard class number and description: 2.2 (Non-Flammable Gas).  UN identification number: UN 1956.  DOT Label required: Non-Flammable Gas.  North American Emergency Response Guidebook Number (1996): 126

SECTION VIII– FIRST AID MEASURES

Skin:  N/A

 

Eye:  N/A

 

Inhalation: No unusual health effects are anticipated after exposure to this product, due to the small cylinder size.  If any adverse symptom develops after over-exposure to this product, remove victim(s) to fresh air as quickly as possible.  Only trained personnel should administer supplemental oxygen and/or cardio-pulmonary resuscitation if necessary.

Ingestion:  N/A

 

General Advice:  Victim(s) who experience any adverse effect after over-exposure to this product must be taken for medical attention.  Take a copy of the label and the MSDS to physician or other health professional with victim(s).
