Excerpt from ERG Guide 116 [Gases - Flammable (Unstable)]:
DO NOT EXTINGUISH A LEAKING GAS FIRE UNLESS LEAK CAN BE STOPPED.
SMALL FIRE: Dry chemical or CO2.
LARGE FIRE: Water spray or fog. If it can be done safely, move undamaged containers away from the area around the fire.
FIRE INVOLVING TANKS: Fight fire from maximum distance or use unmanned master stream devices or monitor nozzles. Cool containers with flooding quantities of water until well after fire is out. Do not direct water at source of leak or safety devices; icing may occur. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks in direct contact with flames. For massive fire, use unmanned master stream devices or monitor nozzles; if this is impossible, withdraw from area and let fire burn. (ERG, 2024)
Shut off supply; if not possible and no risk to surroundings, let the fire burn itself out. In other cases extinguish with powder, carbon dioxide. Combat fire from a sheltered position.
Use fine spray or fog to control fire by preventing its spread and absorbing some of its heat. Stop flow of gas before extinguishing fire. Use water spray to keep fire-exposed containers cool. Do not use halocarbons. Explosive decomposition may occur under fore conditions. Fight fire from protected location or maximum possible distance. Approach fore from upwind to avoid hazardous vapors and toxic decomposition products.
If material on fire or involved in fire: Do not extinguish fire unless flow can be stopped. Do not apply water to point of leak in tank car or container. Use water in flooding quantities as fog. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Use "alcohol" foam, dry chemical or carbon dioxide.
Evacuation: If fire becomes uncontrollable or container is exposed to direct flame - consider evacuation of one-third (1/3) mile radius.
Shut off supply; if not possible and no risk to surroundings, let the fire burn itself out; in other cases extinguish with powder, carbon dioxide.
... React slowly with water ... A harmful concentration of this gas in the air will be reached very quickly on loss of containment.
Closed containers may rupture violently when heated.
· CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper not available or no answer, refer to appropriate telephone number listed on the inside back cover.
· Keep unauthorized personnel away.
· Stay upwind, uphill and/or upstream.
· Many gases are heavier than air and will spread along the ground and collect in low or confined areas (sewers, basements, tanks, etc.).
· ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area.
· All equipment used when handling the product must be grounded.
· Stop leak if you can do it without risk.
· Do not touch or walk through spilled material.
· Do not direct water at spill or source of leak.
· Use water spray to reduce vapors or divert vapor cloud drift. Avoid allowing water runoff to contact spilled material.
· If possible, turn leaking containers so that gas escapes rather than liquid.
· Prevent entry into waterways, sewers, basements or confined areas.
· Isolate area until gas has dispersed.
Excerpt from ERG Guide 116 [Gases - Flammable (Unstable)]:
IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area for at least 100 meters (330 feet) in all directions.
LARGE SPILL: Consider initial downwind evacuation for at least 800 meters (1/2 mile).
FIRE: If tank, rail tank car or highway tank is involved in a fire, ISOLATE for 1600 meters (1 mile) in all directions; also, consider initial evacuation for 1600 meters (1 mile) in all directions. (ERG, 2024)
Immediate precautionary measure
· Isolate spill or leak area for at least 100 meters (330 feet) in all directions.
Large Spill
· Consider initial downwind evacuation for at least 800 meters (1/2 mile).
· If tank, rail tank car or highway tank is involved in a fire, ISOLATE for 1600 meters (1 mile) in all directions; also, consider initial evacuation for 1600 meters (1 mile) in all directions.
Evacuate danger area! Consult an expert! Personal protection: self-contained breathing apparatus. Ventilation. Remove gas with fine water spray.
Evacuate danger area! Consult an expert! Ventilation. Remove gas with fine water spray (extra personal protection: self-contained breathing apparatus).
Stop or control the leak, if this can be done without undue risk. Use water spray to cool and disperse vapors and protect personnel. Releases may ignite spontaneously.
SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.
CAUTION: Silanes are toxic. Avoid contact with skin and eyes. Use effective fume removal device. /Silanes/
SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.
Personnel protection: Avoid breathing vapors. Keep upwind. ... Avoid bodily contact with the material. Do not handle broken packages unless wearing appropriate personal protective equipment. Wash away any material which may have contacted the body with copious amounts of water or soap and water.
Evacuation: ... If material leaking (not on fire) consider evacuation from downwind area based on amount of material spilled, location and weather conditions.

/LABORATORY ANIMALS: Acute Exposure/ In mice, 4 out of 10 animals died following exposure to 9,600 ppm (approx 13,345 mg/cu m) for 4 hours.[Health Council of the Netherlands: Committee on Updating of Occupational Exposure Limits. Silane; Health-based Reassessment of Administrative Occupational Exposure Limits. p.014-5. The Hague: Health Council of the Netherlands, 2000; 2000/15OSH/014.]
/LABORATORY ANIMALS: Acute Exposure/ Rats exposed at 126 ppm for 1 hr were apparently unaffected.[American Conference of Governmental Industrial Hygienists. Documentation of the TLV's and BEI's with Other World Wide Occupational Exposure Values. CD-ROM Cincinnati, OH 45240-1634 2005., p. 1]
/LABORATORY ANIMALS: Acute Exposure/ ... Male ICR mice (n=10/group) were exposed to approximately 1,000 ppm (approx. 1,390 mg/cu m) of silane for 1 hour or 2, 4, or 8 hours. After sacrifice 3 days postexposure, the organs were examined grossly, and histologically (all exposed and non-exposed mice: nasal cavity, lung, liver, kidney, spleen, thymus, bone marrow, and testis; some of the mice: cornea, trachea, thyroid, salivary glands, and oesophagus). Biochemical and hematological parameters examined included alkaline phosphatase, aspartate and alanine aminotransferase, cholinesterase, blood urea nitrogen, sodium, potassium, red blood cell count, and total and differential white blood cell counts. Neither mortality nor exposure-related changes in any of the organs were observed. Biochemical or hematological parameters affected included an increase in red blood cell counts in mice exposed for 8 hours, an increase in blood urea nitrogen in mice exposed for 1 hour and a decrease in the 8-hour exposure group, and a decreased white blood cell count after 1-hour exposure.[Health Council of the Netherlands: Committee on Updating of Occupational Exposure Limits. Silane; Health-based Reassessment of Administrative Occupational Exposure Limits. p.014-5. The Hague: Health Council of the Netherlands, 2000; 2000/15OSH/014.]
/LABORATORY ANIMALS: Acute Exposure/ When male ICR mice were exposed to 2,500, 5,000, 7,500, or 10,000 ppm (approx 3,475, 6,950, 10,425, 13,900 mg/cu m) for 30 minutes, 1 hour, or 4 hours, only in the animals exposed to 10,000 ppm for 4 hours, mortality (ie, 9/12; all within 24 hr) was observed. At autopsy of these animals, increased relative kidney weights, renal tubular necrosis, splenic atrophy, appearance of macrophages with debris of degenerated cells in bone marrow and thymus, and inflammatory changes of the nasal mucosa was seen. In the groups exposed for 30 minutes or 1 hour and sacrificed at week 2, mainly effects on the kidneys were found (tubular interstitial nephrosis in 6/8 and 7/8 animals, respectively). Following exposure to 7,500 ppm (only 30-min exposure), tubular nephrosis was seen in 4/8 animals. The 1- and 4-hour exposures to 5,000 ppm caused tubular interstitial nephritis in 1/8 and 2/8 animals sacrificed at week 2, respectively, and acute renal tubular necrosis in 0/4 and 1/4 animals sacrificed after 2 days, respectively. Concerning the 2,500 ppm groups, the only effect observed was acute renal tubular necrosis in 1/4 animals exposed for 4 hours.[Health Council of the Netherlands: Committee on Updating of Occupational Exposure Limits. Silane; Health-based Reassessment of Administrative Occupational Exposure Limits. p.014-5. The Hague: Health Council of the Netherlands, 2000; 2000/15OSH/014.]
