Introduction
Glutaraldehyde (CAS No: 111-30-8,110-30-8) is a compound with the chemical formula C5H8O2. It has two aldehyde groups and is water soluble oily liquid. This dialdehyde consists of pentane with aldehyde functional groups at C-1 and C-5 positions. It is a clear viscous colorless liquid with pungent odor.Preferred IUPAC name of glutaraldehyde is pentanedial. The other names are glutaraldehyde, glutardialdehyde, glutaric acid dialdehyde, glutaric aldehyde, glutaric dialdehyde and 1,5-pentanedial.
Working Process
Glutaraldehyde is activated with an alkaline buffer such as sodium bicarbonate, when it is in 1% to 2% aqueous solution. Industrial manufacturers that buyglutaraldehyde, must use it within two weeks post activation. It is used for chemical disinfection of dental equipment, bronchoscopes, endoscopes and other clinical instruments. Disinfection of instruments is carried out through it immersion in glutaraldehyde solution with automated washing units, trolley systems or closed troughs.
Applications
- Glutaraldehyde suppliers supply this antimicrobial chemical, which finds disinfection applications inagriculture, hospitals,food storage establishments, food handling, aquaculture and water treatment plants.
- Consumer products’ industries buy glutaraldehyde for adhesives, textiles, paper, leathers, coatings, paints, cleaners, cosmetics, inks and dyes. Industries buy glutaraldehyde for use a tissue fixative in embalming fluids, photographic development fluids, x-raydevelopment fluids and laboratories.
- Glutaraldehyde suppliers supply it for hydraulic fracturing and offshore oil operations.
Health Hazard Summary
Exposure to glutaraldehyde can lead toirritation of the eyes, nose, throat, and skin. Over exposure to glutaraldehyde can result in asthma andallergic skin reactions. Presence of glutaraldehyde vapors could cause coughing, sore throat, burning nose, teary eyes and headache. Exposure to liquid glutaraldehyde could irritate the eyes and lead to permanent eyes damage. It can remove skin’s natural protective oils. Its vapor can irritate the lungs and cause shortness of breath and chest pain. Glutaraldehyde suppliers, manufacturers and end user must be aware of the health hazards posed by the chemical.
Engineering Controls
Glutaraldehyde suppliers, manufacturers and employers must rely on engineering control methods instead ofpersonal protective equipment to prevent overexposure. Control methods include changing work practices, changing the work process and installing ventilation. Chemical containers must be properly covered to prevent evaporation. Exhaust ventilation systems or hoods must be provided as they capture contaminated air before they spread into air, right from its source. Manufacturers and intermediate industries who buy glutaraldehyde must have engineering controls in place.
Personal Protective Equipment
Protective equipment like gloves, face shields or goggles must be worn, when there is possibility of skin contact. Glutaraldehyde resistant protective clothing should be used made of neoprene, butyl rubber, viton or polyvinyl chloride. A respiratoryprotection program should be developed.Anindustrial hygienist should be consulted, to ensure that the equipment isapt and is used rightly.
