Description of necessary first-aid measures 
Immediately flood the eye with plenty of water for at least 15 minutes, holding the eye open. Obtain 
medical attention if soreness or redness persists.  
Wash skin thoroughly with soap and water. Obtain medical attention if irritation persists. 
Dilute by drinking large quantities of water and obtain medical attention.  
Move victim to fresh air. Obtain medical attention immediately for any breathing difficulty. 
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 
Suitable Extinguishing Media 
This preparation 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 pressurized containers and 
surroundings cool with water spray as they may rupture or burst in the heat of a fire. 
Specific hazards arising from the chemical 
Pressurized 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 
Wear appropriate protective clothing. Prevent skin and eye contact. Remove leaking container to a safe 
place. Ventilate the area.  
Environmental Precautions 
Prevent large quantities of the material from entering drains or watercourses. 
Methods and materials for containment and cleaning up 
Contain and absorb using appropriate inert material. Transfer into suitable containers for recovery or 
disposal.

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 and plastic 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. 
Appropriate engineering controls 
Use with adequate ventilation. If this product is used in a pressurized system, there should be local 
procedures for the selection, training, inspection and maintenance of this equipment. When used in large 
volumes, use local exhaust ventilation.  
Individual protection measures 
Not normally required. In oxygen deficient atmospheres, use a self contained breathing apparatus, as an 
air purifying respirator will not provide protection.  
Chemical goggles or safety glasses with side shields.
