1 Formaldehyde Training zN. C. State University zEnvironmental Health & Safety Center

2 Contents zReview of OSHA Formaldehyde Standard (1910.1048) zPotential Health Effects zExposure Control Methods zSigns and Symptoms of Exposure zHygiene Protection zEmergencies and Spill Procedures zMedical Surveillance zRecordkeeping zMSDS

3 OSHA Formaldehyde Standard (1910.1048) zScope: yApplies to all occupational exposures to formaldehyde (i.e.. Formaldehyde gas, its solutions and materials that release formaldehyde)

4 OSHA Formaldehyde Standard (1910.1048)  Requirements: yRequires initial monitoring for employees who may be exposed at or above the action level/STEL yMonitoring whenever sign and symptoms of exposure reported

5 OSHA Formaldehyde Standard (1910.1048)  Requirements: yPeriodic monitoring yIn laboratories, all experiments involving formaldehyde need to be carried out in a certified chemical hood yInitial training: xRecommended for all employees who may come to contact with formaldehyde in their work environment xRequired for anatomy, pathology, & histology

6 OSHA Formaldehyde Standard (1910.1048)  Requirements: yAnnual refresher training: xFor anatomy, pathology and histology labs xAny lab with airborne formaldehyde concentrations at or above 0.1 ppm xRefresher training whenever a new/modified process is introduced in work area xSite specific training by PI/supervisor

7 OSHA Formaldehyde Standard (1910.1048)  Requirements: zAll laboratories using formaldehyde require a written safety plan zSafety plan shall explain methods of safe handling formaldehyde in all process zNCSU written formaldehyde program may be used as a support document for formaldehyde use

8 OSHA Formaldehyde Standard (1910.1048) zPermissible Exposure Limits (PELs) yTWA - Time Weighted Average: x0.75 ppm as an 8-hour TWA ySTEL - Short Term Exposure Limit x2.0 ppm for any 15 minute period during the work period yAction Level x0.5 ppm as an 8-hour TWA

9 OSHA Formaldehyde Standard (1910.1048) zRegulated Areas - yShall be established where airborne formaldehyde concentrations exceed either TWA or STEL yDanger signs shall be posted at entrances yAccess shall be limited to authorized persons DANGER FORMALDEHYDE IRRITANT AND POTENTIAL CANCER HAZARD AUTHORIZED PERSONNEL ONLY

10 Potential Health Effects zInhalation: Repeated or chronic exposure- ymay cause headaches, rhinitis, nausea, drowsiness, respiratory impairment, kidney injury and pulmonary sensitization and tissue damage yMay cause neuropsychological effects including sleep disorders, irritability, altered sense of balance, memory deficits, loss of concentration, and mood alterations

11 Potential Health Effects zInhalation: Carcinogenic Effects yLong-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.

12 Potential Health Effects ySkin Contact xAcute 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 and arms.

13 Potential Health Effects zSkin Contact yChronic Exposure: Prolonged or repeated exposures may cause second degree burns, numbness and itching rash, fingernail damage, hardening or tanning of the skin and sensitization. The dermatitis may be either a sudden blistering reaction or may be delayed several years with eruptions starting on the digital areas, wrists and other body parts.

14 Potential Health Effects zEye Contact yAcute Exposure: Airborne concentrations from 0.05 to 3.0 ppm may cause irritation with redness, itching, pain, blurred vision, and mild tearing. Concentrations from 4 to 20 ppm may cause profuse tearing and damage to the eye. Aqueous solutions effects range from reversible, minor injury and discomfort to severe, permanent corneal damage and loss of sight.

15 Potential Health Effects zEye Contact yChronic Exposure: xEffects depend on the concentration and duration of exposure xEffects are different based on the individual’s sensitivity

16 Signs and Symptoms of Overexposure zWatery eyes zBurning sensations in eyes, nose and throat zSkin rashes zNausea z Coughing zChest tightness zAllergic reactions

17 Exposure Control Methods zEngineering Controls yReduces or eliminates hazard at the source yPreferred method of hazard control xExamples: Using formaldehyde preservative substitute whenever possible Using formaldehyde only in chemical laboratory hoods

18 Exposure Control Methods zAdministrative Controls (Work Practices) yControl between the worker and the source of hazard: xExamples: Keep solution containers of formaldehyde closed when not in use Reduce exposure time

19 Exposure Control Methods zPersonal Protective Equipment (PPE) ySpecialized clothing or equipment worn to protect from hazard yProvides limited protection yRequires proper use and maintenance yThe last choice for exposure control

20 Exposure Control Methods zPersonal Protective Equipment (PPE) yEye protection : xIndirect-vent goggles xface shield worn with goggles for severe exposure

21 Exposure Control Methods zPersonal Protective Equipment (PPE) xGloves : choose gloves and sleeves with proper permeation and degradation ratings, materials such as nitrile or neoprene are recommended xGloves have limited protection and shall be changed as soon as they become contaminated

22 Exposure Control Methods zPersonal Protective Equipment (PPE) xRespiratory protection Used at exposures above PEL or STEL Used only when other control methods are not feasible/effective Used in emergencies Voluntary use (employee’s concern) –Air purifying respirators with chemical cartridge –Air supplied respirators Any respirator selection/use requires EH&S approval

23 Exposure Control Methods zPersonal Protective Equipment (PPE) yApparel: Aprons and sleeves may be worn over lab coats, neoprene and nitrile materials offer excellent resistance to formaldehyde and a wide variety of other chemicals yFor more information on personal protective equipment contact EHSC at 513-1282

24 Hygiene Protection zEmergency Showers ywill be located in areas where employee’s skin may be splashed with solutions containing 1% or greater formaldehyde yEmergency showers require annual inspection and test

25 Hygiene Protection zEmergency Eyewashes yShall be located in areas where employee’s eyes may be splashed with solutions containing 0.1% or greater formaldehyde yEmergency eyewash shall be able to deliver at least 1.5 liters of water per minute (0.4 gpm) for 15 minutes yEyewash stations need weekly test and annual inspection

26 Emergencies and Spill zExposure Incidents yInhalation: leave the area and seek immediate medical attention, report to supervisor ySkin/eye exposure: rinse the effected area/eyes using the emergency eyewash/safety showers for at least 15-minute and seek immediate medical attention (report to supervisor)

27 Emergencies and Spill zInjuries yWhile protecting yourself, try to help by removing the victim to a safe area yReport the incident to the campus police (911) yStay with victim until help arrives

28 Emergencies and Spill zLarge Spills yLeave the area, close the door, call campus police at 911 and inform your supervisor yReport the location and volume of the spill zSmall Spills yNeed to be cleaned by trained people yUse appropriate types of PPE ySeal and contain cleaning debris as hazardous waste

29 Medical Surveillance zInstitute medical surveillance program for all employees exposed to formaldehyde concentrations at or exceeding the Action Level or exceeding the STEL zEmployees who develop signs and symptoms of overexposure  Employees exposed to formaldehyde in emergencies

30 Medical Surveillance zProgram includes: yMedical Disease Questionnaires yPerformed by or under supervision of a licensed physician yMedical Examinations yNo cost to employee

31 Recordkeeping zMedical yKept for duration of employment and 30 years thereafter yArchived at the Student Health Services zMonitoring and exposure assessment data: yKept for 30 years yArchived at EH&S

32 Material Safety Data Sheet (MSDS) zA unique document for a specific chemical, explaining information such as hazards, exposure limits, spill control, and protective equipment in different sections zMust be readily available wherever chemical is being used zManufacturer's responsibility to develop and provide MSDS

33 Additional Resources zOSHA Formaldehyde Program (29 CFR 1910.1048) zOSHA Occupational Exposure to Hazardous Chemicals in Laboratories (29CFR 1910.1450) zNCSU on-line formaldehyde program z isk/formaldehyde isk/formaldehyde zNIOSH pocket guide to chemical hazards zNational Cancer Institute
