3140 Finley Road Downers Grove, IL INTRODUCTION You should already be very familiar with the specific requirements of the OSHA standards. This presentation highlights programs as they relate to potential employee exposures to environmental stressors. It does not cover all aspects of each standard.

3140 Finley Road Downers Grove, IL HAZARD COMUNICATION Hazard Communication Program Container Labeling Material Safety Data Sheet MSDS Program Label The OSHA Standard was written to ensure that employers and employees know about work hazards and how to protect themselves so that the incidence of illnesses and injuries due to hazardous chemicals is reduced.

3140 Finley Road Downers Grove, IL HAZARD COMUNICATION How can workplace exposures be minimized? –Perform a thorough hazard assessment –Be informed about the hazards of the chemicals you use –This information is obtained from MSDSs and labels Communication of hazards to others in area –Hazards –Detecting exposures, symptoms –Protective measures

3140 Finley Road Downers Grove, IL HAZARD COMUNICATION Ensure containers are labeled properly. –Each container of hazardous chemicals must be labeled or marked with: Identity of the chemical Appropriate hazard warnings Name and address of the responsible party

3140 Finley Road Downers Grove, IL HAZARD COMUNICATION Material Safety Data Sheets (MSDS) Prepared by the chemical manufacturer or importer describes: –Physical hazards, such as fire and explosion –Health hazards, such as signs of exposure –Routes of exposure –Precautions for safe handling and use –Emergency and first-aid procedures –Control measures

3140 Finley Road Downers Grove, IL HAZARD COMUNICATION MSDS provides information about the: –Physical and chemical characteristics –Health effects –Exposure limits –Carcinogenicity (cancer-causing) –Identification (name, address, and telephone number) of the organization responsible for preparing the sheet Must be readily accessible to employees in their work area

3140 Finley Road Downers Grove, IL HEARING CONSERVATION

3140 Finley Road Downers Grove, IL Whether a noise is harmful will depend on its intensity, which is measured in decibels. HEARING CONSERVATION decibels Quietest perceivable sound Quiet bedroom Normal conversation Traffic Lawn MowingGrindingChain Sawing Pain Threshold InjuriousIrritating

3140 Finley Road Downers Grove, IL When noise exposures equal or exceed 85 dBA (as an 8-hour TWA), a hearing conservation program must be implemented. HEARING CONSERVATION Hearing Conservation Program Noise exposure monitoring Audiometric testing Hearing protection Employee training Recordkeeping

3140 Finley Road Downers Grove, IL HEARING CONSERVATION Types of Hearing Loss –Conductive –Sensorineural

3140 Finley Road Downers Grove, IL HEARING CONSERVATION Conductive –Not caused by noise exposure –Disorder in the external or middle ear that prevents sound from reaching the inner ear e.g. wax in ear, infection, etc. –Inner ear intact –Non-occupational –Reversible

3140 Finley Road Downers Grove, IL HEARING CONSERVATION Sensorineural –Poor transmission of sound by bone or nerve pathways –Damage to the cochlea and/or auditory nerve –Deep structures of the ear are damaged –Induced by occupational noise –Not reversible

3140 Finley Road Downers Grove, IL Noise can cause other effects on the body in addition to hearing loss. HEARING CONSERVATION Permit Condition s Increased blood pressure Increased pulse rate FatigueFatigue Other Health Effects Other Health Effects Heart palpitations NervousnessNervousness Decreased coordination Digestive problems Decreased concentration

3140 Finley Road Downers Grove, IL There are two sound measuring instruments typically used for noise monitoring. HEARING CONSERVATION Sound Level Meters Noise Dosimeters Area Sampling Personal Sampling

3140 Finley Road Downers Grove, IL HEARING PROTECTION Noise Reduction Rating (NRR) A rating that is assigned to specific personal hearing protection that gives an estimated reduction when the protection is worn properly. Only valid if HP worn correctly NO

3140 Finley Road Downers Grove, IL There are four methods for determining the adequacy of hearing protection. The most common is: HEARING PROTECTION Manufacturer’s Noise Reduction Rating = 25 dBA Employee’s Exposure = 100 dBA (8-hour TWA) Attenuation = 100 dBA - (25 dBA - 7dBA)/2 = 91 dBA Attenuation calculated using OSHA method Will not work

3140 Finley Road Downers Grove, IL PERSONAL PROTECTIVE EQUIPMENT

3140 Finley Road Downers Grove, IL PERSONAL PROTECTIVE EQUIPMENT Basic Principles: –Must protect response personnel from exposure –Must know what chemicals are involved in exposure –Must know general concentration of exposure –Must select appropriate PPE materials –Must know limitations

3140 Finley Road Downers Grove, IL Selection and Use –Prepare ahead of time! –There is not one material that protects against all chemicals! –Protect eyes, head, face, hands, body, feet PERSONAL PROTECTIVE EQUIPMENT

3140 Finley Road Downers Grove, IL Consider performance requirements when selecting: –Aging resistance –Chemical resistance –Cleanability –Color –Comfort –Durability –Flexibility –Strength –Size –Service Life –Thermal Limits PERSONAL PROTECTIVE EQUIPMENT

3140 Finley Road Downers Grove, IL PERSONAL PROTECTIVE EQUIPMENT Chemical Resistance Permeation Degradation Penetration

3140 Finley Road Downers Grove, IL Permeation –Diffusion of chemicals through intact material PERSONAL PROTECTIVE EQUIPMENT

3140 Finley Road Downers Grove, IL Degradation –A loss or change in one or more physical properties of a protective clothing material due to contact with a chemical –A chemical process PERSONAL PROTECTIVE EQUIPMENT

3140 Finley Road Downers Grove, IL Penetration –The flow of a chemical through closures, porous materials, seams and pinholes or other imperfections in a protective clothing material on a non-molecular level –A physical process PERSONAL PROTECTIVE EQUIPMENT

3140 Finley Road Downers Grove, IL Must know the type of chemical you are up against, as chemicals will “break through” incompatible materials. Breakthrough times (min.) are the times observed from the start of the test to first detection of the chemical on the other side of the sample material. PERSONAL PROTECTIVE EQUIPMENT
