Hazard Communication

OSHA's 1910.1200, Hazard Communication standard is also called the HazCom Standard. It requires the classification of potential hazards of chemicals, and communicating information concerning hazards and appropriate protective measures to employees, The standard includes provisions for:

  • developing and maintaining a written hazard communication program for the workplace, including lists of hazardous chemicals present;
  • labeling containers of chemicals in the workplace, as well as containers of chemicals being shipped to other workplaces;
  • preparation and distribution of Safety Data Sheets (SDSs) to workers and downstream employers; and
  • development and implementation of worker training programs regarding hazards of chemicals and protective measures.

The standard also requires manufacturers and importers of hazardous chemicals to provide Safety Data Sheets to users of the chemicals describing potential hazards and other information. They must also attach hazard warning labels to containers of the chemicals. Employers must make SDSs available to workers. They must also train their workers in the hazards caused by the chemicals workers are exposed to and the appropriate protective measures that must be used when handling the chemicals.

For additional training on this topic, be sure to check out OSHAcademy course 705 - Hazard Communication Program.

The Bloodborne Pathogens (BPP)

Bloodborne Pathogens

OSHA's 1910.1030, Bloodborne Pathogens Standard requires employers to protect workers from infection with human bloodborne pathogens in the workplace. The standard covers all workers with "reasonably anticipated" exposure to blood or other potentially infectious materials (OPIM).

It requires that information and training be provided:

  • before the worker begins work that may involve occupational exposure to bloodborne pathogens
  • annually
  • before a worker is offered a hepatitis B vaccination

The Bloodborne Pathogens standard also requires advance information and training for all workers in research laboratories who handle human immunodeficiency virus (HIV) or hepatitis B virus (HBV).

The employer must develop a written exposure control plan (ECP) to provide a safe and healthy work environment and is allowed some flexibility in accomplishing this goal. Among other things, the ECP requires employers to:

  • Make an exposure determination.
  • Establish procedures for evaluating incidents.
  • Determine a schedule for implementing the standard’s requirements, including engineering and work practice controls.
  • Provide and pay for appropriate PPE for workers with occupational exposures.

Although the OSHA standard only applies to bloodborne pathogens, the protective measures in the standard (e.g., ECP, engineering and work practice controls, administrative controls, PPE, housekeeping, training, post-exposure medical follow-up) are the same measures for effectively controlling exposure to other biological agents.

For additional training on bloodborne pathogens safety, take Course 655 Bloodborne Pathogens in the Workplace and Course 755 Bloodborne Pathogens Program Management.

Personal Protective Equipment (PPE)

Proper Dress and PPE/Lab Safety 1

The OSHA 1910.132 standard requires requires employers to provide and pay for PPE and ensure that it is used wherever hazards are encountered in a manner capable of causing injury or impairment in the function of any part of the body through absorption, inhalation or physical contact. The types of hazards covered include:

  • hazards of processes or environment
  • chemical hazards
  • radiological hazards
  • mechanical irritants

In order to determine whether and what PPE is needed, the employer must assess the workplace to determine if hazards are present, or are likely to be present, which necessitate the use of PPE. Based on that assessment, the employer must select appropriate PPE that will protect the affected worker from the hazards and select PPE that properly fits each affected employee.

Employers must provide training for workers required to use PPE that addresses the following topics:

  • When PPE is necessary
  • What PPE is necessary
  • How to properly don, doff, adjust, and wear PPE
  • The limitations of the PPE, and
  • The proper care, maintenance, useful life and disposal of the PPE

Although it's not required by OSHA, it's important to discuss "why" it is important to use specific PPE by emphasizing the consequences of improper use. Affected employees must also demonstrate an understanding of the training and ability to properly use specific PPE.

3. Which of the following important PPE training topics is not specifically required by OSHA, but should be included in all PPE training?

a. why PPE is necessary
b. what PPE is necessary
c. the limitations of the PPE
d. the proper care and maintenance of PPE

Respiratory Protection

OSHA's 1910.134, Respiratory Protection Standard requires that a respirator be provided to each worker when such equipment is necessary to protect the health of such individual. The employer must provide respirators that are appropriate and suitable for the purpose intended. The employer is responsible for establishing and maintaining a respiratory protection program that includes the following:

  • selection of respirators for use in the workplace;
  • medical evaluations of workers required to use respirators;
  • fit testing for tight-fitting respirators;
  • proper use of respirators during routine and emergency situations;
  • procedures and schedules for cleaning, disinfecting, storing, inspecting, repairing and discarding of respirators;
  • procedures to ensure adequate air quality, quantity, and flow of breathing air for atmosphere-supplying respirators;
  • training of workers in respiratory hazards that they may be exposed to during routine and emergency situations;
  • training of workers in the proper donning and doffing of respirators, and any limitations on their use and maintenance; and
  • regular evaluation of the effectiveness of the program.
