SMALL FIRE: Use water. Do not use dry chemicals or foams. CO2 or Halon® may provide limited control.

LARGE FIRE: Flood fire area with water from a distance. Do not move cargo or vehicle if cargo has been exposed to heat. If it can be done safely, move undamaged containers away from the area around the fire. Do not get water inside containers: a violent reaction may occur.

FIRE INVOLVING TANKS, RAIL TANK CARS OR HIGHWAY TANKS: Cool containers with flooding quantities of water until well after fire is out. Dike runoff from fire control for later disposal. 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)

If material on fire or involved in fire: Use suitable dry powder. Cool all affected containers with flooding quantities of water. Do not use water on material itself. Use water in flooding quantities as fog. Keep run-off water out of sewers and water sources.

· 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.

· Ventilate closed spaces before entering, but only if properly trained and equipped.

· Keep combustibles (wood, paper, oil, etc.) away from spilled material.

· Do not touch damaged containers or spilled material unless wearing appropriate protective clothing.

· Use water spray to reduce vapors or divert vapor cloud drift.

· Prevent entry into waterways, sewers, basements or confined areas.

Excerpt from ERG Guide 143 [Oxidizers (Unstable)]:

IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids.

SPILL: Increase the immediate precautionary measure distance, in the downwind direction, as necessary.

FIRE: If tank, rail tank car or highway tank is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2024)

Immediate precautionary measure

· Isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids.

· For highlighted materials: see Table 1 - Initial Isolation and Protective Action Distances.

· For non-highlighted materials: increase the immediate precautionary measure distance, in the downwind direction, as necessary.

· If tank, rail tank car or highway tank is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions.

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.

If material not on fire and not involved in fire: Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Do not use water. Keep material dry.

Personnel protection: Avoid breathing vapors or dusts. Avoid bodily contact with the material. ... Do not handle broken packages unless wearing appropriate personal protective equipment. If contact with the material anticipated, wear appropriate chemical protective clothing. Wash away any material which may have contacted the body with copious amounts of water or soap and water. Avoid breathing dusts, and fumes from burning material. ...

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.

/SIGNS AND SYMPTOMS/ In contact with eyes these substances produce inflammation. /Peroxides/

/SIGNS AND SYMPTOMS/ Acute intoxication can occur in the initial phase in a course of therapy, but also at any point of time during long-lasting treatment or after an acute overdose. At plasma levels between 1.5 and 2.5 mmol/L, signs of toxicity include anorexia, dry mouth, nausea, vomiting, diarrhea, tremor of the hands, faintness of musculature, thirst, leucocytosis, and concentration and memory disturbances (especially with older people). These phenomena are often seen in the initial phase of a course of treatment and usually disappear when treatment continues, except with the tremor of the hands. In elderly people, reversible delirious conditions can occur with confusion, restlessness, and ataxia. At plasma levels above 2.5 mmol/L, serious toxic symptoms occur; fasciculations, muscle contractions, hyperreflexia and hypertonia, drowsiness, confusion, sometimes epileptiform insults, hypotension, coma, collapse. Independent of the plasma level, changes can occur in the ECG and in the EEC, with symptoms such as polyuria and polydipsia, seldom nephrogenic diabetes insipidus, ulcers of the leg, enhancement of acne and psoriasis, transient hyperglycemia, pruritus, and a metal taste. In about 5% of the cases, a (usually reversible) hypothyroidia develops. /Li+/

/SIGNS AND SYMPTOMS/ A ... selective action of Li+ is to inhibit inositol monophosphatase and thus interfere with the phosphatidylinositol pathway ... This effect can lead to decr in cerebral inositol concn, which can be detected with magnetic resonance spectroscopy in human brain tissue. However, the physiological consequences of this effect remain uncertain, including interference with neurotransmission mechanisms that are mediated by the phosphatidylinositol pathway ... /Li+/

/SIGNS AND SYMPTOMS/ The prolonged use of Li+ causes a benign and reversible depression of the T wave of the ECG, an effect not related to depletion of Na+ or K+. /Li+/
