Highlights of IH Programs and OSHA Standards


INTRODUCTION

• Hazard Communication• Hearing Conservation• Personal Protective Equipment• Respiratory Protection• Heat Stress• Cold Stress• Confined Spaces• Ergonomics• Radiation


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.


HAZARD COMUNICATION

Hazard Communication

Program

Container Labeling

Material SafetyData Sheet

MSDSProgramLabel

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.


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


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


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


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


HEARING CONSERVATION


Whether a noise is harmful will depend on its intensity, which is measured in decibels.

When noise exposures equal or exceed 85 dBA (as an 8-hour TWA), a hearing conservation program must be implemented.


Hearing Conservation Program

• Noise exposure monitoring• Audiometric testing• Hearing protection• Employee training• Recordkeeping



• Types of Hearing Loss – Conductive – Sensorineural



• 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



• 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


Noise can cause other effects on the body in addition to hearing loss.

There are two sound measuring instruments typically used for noise monitoring.

HEARING PROTECTION

• Earmuffs

• Ear Plugs


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


There are four methods for determining the adequacy of hearing protection. The most common is:

HEARING PROTECTION

Manufacturer’s Noise Reduction Manufacturer’s Noise Reduction Rating = 25 dBARating = 25 dBA

Employee’s Exposure = 100 dBA Employee’s Exposure = 100 dBA (8-hour TWA)(8-hour TWA)

Attenuation = 100 dBA - (25 dBA - 7dBA)/2 = 91 dBAAttenuation = 100 dBA - (25 dBA - 7dBA)/2 = 91 dBA

Attenuation calculated using OSHA method

Will not work


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


• Selection and Use– Prepare ahead of

time!– There is not one

material that protects against all chemicals!

– Protect eyes, head, face, hands, body, feet



• Consider performance requirements when selecting:

– Aging resistance– Chemical resistance– Cleanability– Color– Comfort– Durability

– Flexibility – Strength– Size– Service Life– Thermal Limits




• Chemical Resistance

Permeation

Degradation

Penetration


• Permeation

– Diffusion of chemicals through intact material



• 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



• 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



• 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.
