Proper Handling of Chemicals and Liquid Resins By Randy Reynolds Safety hazards associated with using chemicals and liquid photopolymer resins can be minimized by following the recommendations in the materials safety data sheets (MSDS) literature and utilizing the proper Personal Protective Equipment (PPE). Implementation of some general guidelines for good industrial hygiene and safe work practices is advised when using the chemicals and liquid photopolymer resins. The following specifics apply: Skin Protection: Skin contact is best avoided by wearing protective gloves. 1. Disposable gloves work very well. 2. Seamless and vinyl gloves also offer good protection for short usage as long as they are cleaned between uses. 3. It must be understood that gloves do not last forever and should be replaced when necessary. Clean hands are important, so as not to spread chemicals to other body parts. 4. Hands should be washed after removing gloves—especially before leaving the plateroom. Clothing: Contaminated clothing should be removed and laundered before reuse. If cleaned at home, these clothes should be washed separate to prevent any cross contamination. If irritation occurs, the incident should be reported promptly to medical or first aid personnel. Eye Protection: Eyes can be easily irritated or damaged, so special care needs to be taken to prevent chemicals from splashing into someone’s eyes. Safety glasses should be worn at all times when using the chemicals or liquid photopolymer resins. Liquid photopolymer resins are processed using UV light exposure units. Exposure to the eyes by UV light can cause photokeratitis. Symptoms include increased tears and a feeling of pain that has been likened to having sand in the eyes. UV protective glasses should be worn during testing and maintenance of the UV light source. Inhalation: Areas in which liquid photopolymers and chemicals are being used should be adequately ventilated. Inhalation can occur from exposure to dust, mist, fumes, and/or vapors. Exposure must be kept below the levels prescribed by the Occupational Safety and Health Administration (OSHA). See the OSHA venting requirements for their standards. Ingestion: Food and drink should never be stored, prepared, or consumed in areas where they may be exposed to any industrial processing chemicals. Good Housecleaning: Maintain good housekeeping practices throughout the plant. 1.Eliminate handling problems and abuses, plus carelessness in the work area. 2.Clean spills right away—using proper PPE. A clean operation will prevent chemical exposures. Chemicals and liquid photopolymer resins should be given the same consideration that other industrial chemicals are given. Safe work practices and operation should always be used. Waste chemicals should be disposed of properly in accordance with local, state and federal regulations. Specific information on handling and disposal can be found in the product’s MSDS sheets.
