Other Preventive Measures

Precautions for safe handling: Avoid contact with skin and eyes. Avoid inhalation of vapor or mist.
Appropriate engineering controls: Avoid contact with skin, eyes and clothing. Wash hands before breaks and immediately after handling the product.
Gloves must be inspected prior to use. Use proper glove removal technique (without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands.
Wear goggles or face shield. Wear protective clothing (long-sleeve shirt and long pants, socks with shoes and chemical resistant gloves such as water proof gloves. Wash hands before eating, drinking, chewing gum using tobacco or using the toilet. Remove contaminated clothing and wash clothing before reuse. /Emulso Germicidal Bowl Cleaner Disinfectant/
FIRST AID: Have the product container or label with you when calling a poison control center or doctor or going for treatment. IF SWALLOWED: CaIl a poison control center or doctor immediately for treatment advice. Have person sip a glass of water if able to swallow. Do not induce vomiting unless told by a poison control center or doctor. Do not give anything by mouth to an unconscious person. IF IN EYES: Hold eye open and rinse slowly and gently with water for 15-20 minutes. Remove contact lenses, if present after the first 5 minutes, then continue rinsing. Call a poison controi center or doctor for treatment advice. IF ON SKIN OR CLOTHING: Take off contaminated clothing. Rinse skin immediately with plenty of water for 15-20 minutes. Call a poison control center or doctor for treatment advice. IF INHALED: Move person to fresh air. If person is not breathing, call 911 or an ambulance and then give artificial respiration. .. Call a poison control center or doctor for further treatment... /Emulso Germicidal Bowl Cleaner Disinfectant/
Hydrochloric acid should be manufactured in closed systems; particular attention should be paid to the detection of leaks ... When handling ... (loading, unloading, and decanting), measures should be taken to avoid splashes or the inhalation of vapors ... Difficult operations should be carried out in fume cupboards or under exhaust ventilation and an abundant supply of water should always be available ... Workers should never enter tanks or other vessels that have contained hydrochloric acid until ... they have been cleaned. /Hydrochloric acid/
Aqueous scrubbers are used to control hydrogen chloride emissions from vent stacks and other sources. /Hydrogen chloride/
If material not involved in fire: Keep material out of water sources, and sewers. Build dikes to contain flow as necessary. Use water spray to knock down vapors. Neutralize spilled material with crushed limestone, soda ash, or lime. /Hydrochloric acid/
If material not involved in fire: Keep material out of water sources and sewers. Attempt to stop leak if without undue personnel hazard. Use water spray to knock-down vapors. Neutralize spilled material with crushed limestone, soda ash, or lime. Do not use water on material itself. /Hydrogen chloride, anhydrous; Hydrogen chloride, refrigerated liquid/
Personal 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. /Hydrochloric acid; Hydrogen chloride, anhydrous; Hydrogen chloride, refrigerated liquid/
SRP: The scientific literature for the use of contact lenses by industrial workers is inconsistent. The benefits 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.
SRP: When working with strong solutions of acids or bases or other caustic or corrosive materials, always wear a full face mask. When working with caustic or corrosive gases or vapors, a full face mask will not protect the eyes or prevent inhaling the material. A full face respirator is required. /Hydrochloric acid/
SRP: Contaminated protective clothing should be segregated in a manner such that there is no direct personal contact by personnel who handle, dispose, or clean the clothing. The completeness of the cleaning procedures should be considered before the decontaminated protective clothing is returned for reuse by the workers. Contaminated clothing should not be taken home at the end of shift, but should remain at employee's place of work for cleaning.
SRP: Local exhaust ventilation should be applied wherever there is an incidence of point source emissions or dispersion of regulated contaminants in the work area. Ventilation control of the contaminant as close to its point of generation is both the most economical and safest method to minimize personnel exposure to airborne contaminants. Ensure that the local ventilation moves the contaminant away from the worker.
The worker should immediately wash the skin when it becomes contaminated. /Hydrochloric acid solution/
Work clothing that becomes wet or significantly contaminated should be removed or replaced. /Hydrochloric acid solution/
Evacuation: If material leaking (not on fire) consider evacuation from downwind area based on amount of material spilled, location and weather conditions. /Hydrogen chloride, anhydrous/
Evacuation: If fire is prolonged and material is confined in the container- consider evacuation of one (1) mile radius. If fire becomes uncontrollable or container is exposed to direct flame-consider evacuation of one (1) mile radius. /Hydrogen chloride, refrigeratd liquid/
Emergency responders ... should be trained and appropriately attired before entering the Hot Zone. If the proper equipment is not available, or if rescuers have not been trained in its use, assistance should be obtained from a local or regional HAZMAT team or other properly equipped response organization.
