OSHA FORMALDEHYDE STANDARD (29 CFR 1910.1048) The employer will establish and maintain an accurate record of the following: • All measurements taken to monitor employee exposure to formaldehyde. • If no exposure monitoring is performed, the data used to determine that monitoring is not required. • Medical surveillance information • Respirator fit testing information OSHA FORMALDEHYDE STANDARD (29 CFR 1910.1048) RECORDKEEPING • Exposure records and determinations: at least 30 years • Medical records: the duration of employment plus 30 years • Respiratory fit test records: until replaced by more recent a record POTENTIAL HEALTH EFFECT - INHALATION Air Concentration (ppm) Reported Health Effects • 0 - 0.5 • None • Odor threshold • 0.05 - 1.50 • Eye sensation/irritation • 0.05 - 2.0 • Irritation of the nose and throat • 0.10 - 5.0 • Difficulty in breathing, burning sensation in the nose and throat, and coughing POTENTIAL HEALTH EFFECT - INHALATION Air Concentration (ppm) Reported Health Effects • 25 - 50 • Tissue damage and serious respiratory tract injury such as pneumonitis. Associated symptoms may include sneezing, wheezing, chest constriction, bronchitis, headache excessive thirst, weakness, palpitations, nausea and vomiting • 50 - 100 • Pulmonary edema/inflammation - severe lower airway effects • 100 • Death. POTENTIAL HEALTH EFFECTS - INHALATION Chronic Exposure: • Repeated or prolonged exposure may cause headache, rhinitis, nausea, drowsiness, respiratory impairment, kidney injury and pulmonary sensitization. • Neuropsychological effects may include sleep disorders, irritability, altered sense of balance, memory deficits loss, of concentration, and mood alterations. • Menstrual disorders and secondary sterility have occurred in women. POTENTIAL HEALTH EFFECTS - INHALATION Carcinogenic Effects: • Long-term exposure to formaldehyde is reported to be associated with an increased risk of cancer of the nose and accessory sinuses and nasopharyngeal and oropharyngeal cancer in humans. POTENTIAL HEALTH EFFECTS - INGESTION Acute Exposure: • Ingestion of formaldehyde solutions may cause burning of the mouth, throat and stomach, difficulty swallowing, nausea, vomiting and diarrhea, severe abdominal pain, headache, hypertension, vertigo, stupor, convulsions, unconsciousness and coma. May also cause damage to the liver, heart, brain, spleen, pancreas, kidney, and central nervous system. Mean fatal dose in humans is 1-2 ounces of a 37% solution. Chronic Exposure • Repeated ingestion of small amounts of formaldehyde may cause gastrointestinal irritation, vomiting, and dizziness. POTENTIAL HEALTH EFFECTS - SKIN CONTACT Acute Exposure: • Vapors or solutions may cause smarting, white discoloration, roughness, hardness anesthesia, and first degree burns. In previously exposed individuals subsequent exposures may result in a sensitization dermatitis characterized by the sudden eruption of blisters on the eyelids, face, neck, scrotum and arms. Chronic Exposure • Prolonged or repeated exposures may cause second degree burns, numbness, and itching rash, fingernail damage, hardening of tanning of the skin and sensitization. The dermatitis results from chronic exposure to formaldehyde may be either a sudden blistering reaction, or may be delayed several years with eruptions starting on the digital areas, wrists and other parts of the body POTENTIAL HEALTH EFFECTS - Eye Contact Acute Exposures • Airborne concentrations from 0.05 - 3.0 ppm may cause irritation with redness, itching, pain, blurred vision, and mild tearing. Concentrations from 4 - 20 ppm may cause profuse tearing and damage to the eye. Aqueous solutions effects range from transient, minor injury and discomfort to severe, permanent corneal pacification and loss of sight. Chronic Exposure • Effects depend on the concentration and duration of exposure. Reporting Symptoms • Employees will immediately report to their manager, other supervisory personnel, or site medical personnel, the development of any adverse signs or symptoms suspected of being related to formaldehyde exposure. MEDICAL SURVEILLANCE PROGRAM General • The employer shall institute medical surveillance programs for all employees who: – are exposed to formaldehyde concentrations at or above the Action Level or above the STEL – develop signs and symptoms of overexposure to formaldehyde (see MSDS) – are exposed to formaldehyde in an emergency • All medical procedures will be performed by or under the supervision of a licensed physician and will be provided without cost to the employee, without loss of pay, and at a reasonable time and place. MEDICAL SURVEILLANCE PROGRAM Medical Surveillance • Administration of a medical disease questionnaire and an evaluation of the questionnaire by a physician to determine whether a medical examination is necessary (employees not wearing respirators) will be made available to employees: – prior to assignment to a job where formaldehyde exposure is at or above the action level or above the STEL and annually thereafter – promptly upon determining that an employee is experiencing signs and symptoms indicative of possible overexposure to formaldehyde MEDICAL SURVEILLANCE PROGRAM Medical Examinations • Medical examinations will be given to any employee when: – based on the information provided on the medical questionnaire, the physician feels the employee may be at increased risk from exposure to formaldehyde – the employee is required to a wear respirator to reduce exposure to formaldehyde (see Respiratory protection Policy) • Medical examinations will be made available as soon as possible to employees exposed to formaldehyde in an emergency MEDICAL SURVEILLANCE PROGRAM Physician’s Written Opinion • For any examination required by the standard, the employer will obtain a written opinion from the examining physician discussing only those findings relating to occupational exposures to formaldehyde • The written opinion will include: – physician’s opinion as to whether the employee has a medical condition that would increase the risk of material impairment of health with exposure to formaldehyde – recommendations on limiting employee’s exposure or changes inure of personal protective equipment – a statement that the employee has been informed by the physician of any medical conditions that would be aggravated by exposure to formaldehyde and whether there is need for further examination or treatment MEDICAL SURVEILLANCE PROGRAM Physician’s Written Opinion (Cont'd) • The employer will retain the results of the medical examination and tests conducted by the physician in records • The employer will provide a copy of the physician’s written opinion to the affected employee within 15 days of its receipt PERSONAL PROTECTIVE CLOTHING AND EQUIPMENT Purpose • To provide employees with a means of protecting themselves against unnecessary exposures to formaldehyde • Skin Contact: Protective gloves, sleeves, aprons • Eye Contact: Safety glasses/goggles, face shields • Inhalation: Local exhaust ventilation (LEV), respirators PERSONAL PROTECTIVE CLOTHING AND EQUIPMENT Proper Use • Personal protective clothing and equipment can only be effective if it is used properly. – Select the appropriate type of clothing or equipment (e.g. gloves, respirators, LEV) according to Hazard Assessment performed by supervisor for PPE. – Properly maintain and store personal protective equipment after use. – Replace defective or damaged personal protective equipment such as safety glasses, gloves, or respirator components. Mechanical equipment such as LEV can be effectively repaired. PERSONAL PROTECTIVE CLOTHING AND EQUIPMENT Limitations • Personal protective equipment appropriate for use with one substance may be totally inappropriate for use with another substance (e.g. respirators, gloves). Inappropriate use of personal protective equipment may result in unnecessary exposures or injury • Know the expected service life of personal protective equipment and replace it as necessary. – For respirator cartridges utilizing adsorption as the filtration mechanism, when all available collection sites have been filled, “break through” occurs and contaminants will pass through the cartridge. – Likewise, gloves will provide protection for only specific periods of time before the contaminant permeates through the glove material and “breakthrough” occurs.
