Industrial Hygiene Industrial Hygiene is defined as:

The science and art devoted to the anticipation, recognition, evaluation, control, and management of those environmental factors or stresses, arising in or from the workplace, which may cause sickness, impaired health and well-being, or significant discomfort and inefficiency among workers or among citizens of the community.

Primary Objective To protect the health and well

being of employees by eliminating or reducing health hazards that arise from the workplace environment.

Health Hazards Chemical Biological (e.g., bacterial, viral, insects,

animals, allergens) Physical (e.g., radiation, pressure, noise

vibration, temperature) Ergonomic (e.g., repetitive motion, body

stress)

Legal Aspects ofOccupational Health & Industrial Hygiene

I. Occupational Safety and Health Administration (OSHA), under the Department of Labor

II. Workers Compensation

III. Lawsuits

Overview of OSHA The act created:

A. OSHA B. NIOSHC. OSHRCD. OSHA Legislation

OSHA – The Agency Responsible For:

1. Promulgation Occupational Health and Safety Standards

2. Authorized to inspect workplaces and issue citations and civil penalties to employers who are not in compliance.

NIOSH – National Institute of Occupational Safety and

Health

1. Is responsible for research on worker health and safety. NIOSH also recommends new standards to OSHA and supplies OSHA with scientific and technical expertise for the rule making process.

OSHCR – The Occupational Safety and Health Review Commission

1. Set up as an independent agency having the responsibility to try OSHA cases and to hear appeals from decisions of administrative law judges.

The “OSHA” Legislation1. Employer Duties ( General )

Each employer shall furnish to each of his employees, a place of employment which is free from recognized hazards that are causing or are likely to cause death or serious physical harm to his employees.Every employer is required and obliged to comply with the requirements composed by the act.

The “OSHA”Legislation

2. OSHA Standards

OSHA adapts and develops broad standards that apply to all industries.

OSHA Standards

These may be:

A. Performance Standards which state the objective to be obtained

or the hazard to be abated. These standards do not specify

the method of abatement or control.

OSHA Standards

B. Specification Standards

These describe the specific means of hazard abatement. For example:

The PEL’s (permissible exposure limits)

Workplace Inspections

OSHA inspections are made to determine whether employers comply with OSHA Standards, OSHA Regulations, and the general duty clause. Inspectors can issue citations which result in fines.

Know the Law1. The U.S. Department’s Wage and

Hour Division enforces federal laws that regulate the hours and times adolescents may work.

2. Teens between 14 and 15 years old may work only outside school hours and between 7 am. and 7 pm. They are limited to 18 hours of work in a school week and 40 hours (eight hours each day) in a non-school week. Exceptions are made for those who participate in school supervised and administered “work experience” programs.

3. Youths under age 18 may not work in manufacturer and storage of explosives; slaughterhouses; jobs that require use of power-driven machines and cutters; radioactive operations; mining; logging and saw milling; brick and tile manufacturing; roofing; and excavation and demolition.

4. Youths between ages 16 and 17 are also prohibited from driving motor vehicles or working as outside helpers on motor vehicles as part of their job.

Types of Work Associated with

Teen Work – Related Injuries1. Working in and around motor vehicles:

Tractors used on farms, backhoes, bulldozers, loaders, etc.

3. Working near electrical equipment:working near overhead power lines, working on roofs, operating boomed vehicles, etc.

Types of Work Associated with Teen Work – Related Injuries

5. Working jobs with fall hazards:using ladders and scaffolds, working on structures near openings, tree trimmings, etc.

6. Working around cooking appliances:cooking in restaurants, servicing cooking equipment, etc.

7. Working jobs requiring manual lifting:working in warehouses, furniture delivery, stocking, etc.

Worker’s Compensation The first law which dealt with the health of

workers, as a result of there work was the English Factory Acts of 1833. These acts required that employers show concern for the health of their employees.This concern however, was directed toward providing compensation for accidents. The laws did not focus on controlling the causes of these accidents.

Worker’s Compensation These laws lead to what we now have in

the U.S. - Worker’s Compensation Acts in each State. These laws are based on their doctrine of exclusivity, which limits the common law remedy that the injured employee can pursue.

Worker’s Compensation

In other words, in return for agreeing to forgo other legal remedies, workers are guaranteed a swift and sure payment, which covers loss of wages and medical expenses.

Liability 1. Torts – a private or civil wrong or injury.

2. Negligence – conduct which falls below the standard established by law for the protection of others against unreasonable risk of harm.

3. Intentional or fraudulent misrepresentations.

4. Breach of Contract – the deliberate breaching of the agreed upon circumstances or conditions.
