Overview

OCCUPATIONAL SAFETY AND HEALTH                         1926 Subpart D

Overview for Subpart D
Occupational Health and Environmental Controls

General and specific components of a safety and health program are included in this subpart. The wide range of topics covers first aid and lighting to chemical exposures and radiation.

The general standards address programs and training in, Medical Services and First Aid (1926.50), Sanitation (1926.51), Hazard Communication (1926.59), Hazardous Waste Operations and Emergency Response (1926.66), and Process Safety Management of Highly Hazardous Chemical (PSM)(1926.64). Several of these standards are referenced in various paragraphs of the 1926 standards. For instance, the standard for eye washing facilities found at 1926.51(g) applies to all phases of construction such as site work, concrete placement and demolition. This standard may be reiterated in a paragraph such as, Formaldehyde (1926.1148 (h)(3)) "If there is any possibility that an employee's eyes may be splashed with solutions containing 0.1 percent or greater formaldehyde, the employer shall provide acceptable eyewash facilities with the immediate work area for emergency use." Or this standard may be used with Hazard Communication (1926.59(g)(x)) when the Material Safety Data Sheet requires 15 minutes of flushing of the eye.

Specific standards apply to chemicals such as Lead (1926.62) and Personal Exposure Limits (PEL's) (1926.55); lighting in Illumination (1926.56); breathing zone air quality in Ventilation (1926.57) and Criteria for Design and Construction for Spray Booths (1926.66); abrasive blasting/grinding in Ventilation (1926.57) and lasers in Nonionizing Radiation (1926.54).

The list of the 50 most frequently cited standards from January 1, 1990 to April 1, 1996 (as shown in Appendix B) includes several of the Hazard Communication paragraphs as the most cited standards. These requirements apply to or are referenced throughout the 1926 standards. For instance, 1926.103 Respiratory Protection, requires "The chemical and physical properties of the contaminant, as well as the toxicity..." these properties are stated on the Material Safety Data Sheets (MSDS). Section 1926.150 Fire Protection requires "...the development of a fire protection program..." to develop this program, properties such as flammability and reactivity of substances to be used must be known and are available from the MSDS.

The work practices and control methods for the hazards in this Subpart are explained in variety of ways. The PSM (1926.64) standard has examples of block flow diagrams. The lead standard (1926.62) has Medical Surveillance Guidelines. The Hazardous Waste Operations and Emergency Response (1926.65) lists the components of a comprehensive site safety and health plan. Also, illustration D-1 shows training time for those working on hazardous waste sites covered by section 1926.65 and illustration D-2 addresses asbestos (1926.1101).


A summary of this Subpart follows.

This subpart contains general and specific requirements for a safety and health program.

The general requirements are:

    chemical emergency, in section 65;
    Hazardous waste operations and emergency response to chemicals and hazardous substances(see paragraph q) are in this section.

    chemical information, in section 59;
    This is the Hazard Communication standard that has provisions for a written program that includes training, labeling and availability and use of Material Safety Data Sheets.

    chemicals: gases, vapors, fumes, dusts and mists, the personal exposure limits (PEL's), in section 55;
    Exposure by inhaling, ingestion, skin or other contact must be controlled by engineering, administrative or personal protective equipment.

    drinking water and cups, in section 51;
    An adequate supply of drinking quality water must be available.

    lighting, in section 56;
    General construction lighting must be at least 5 foot-candles.

    medical services and first aid, in section 50;
    Arrangements are to be made prior to the start of the project for prompt medical attention.

    noise and the hearing conservation program in section 52;
    Engineering, administrative or hearing protection must be provided.

    shipping labels, in section 61;
    Packages, freight containers, freight cars, etc., with the Department of Transportation's hazardous materials labels or making must be visibly placarded until the packaging is removed of potential hazards.

    rodents and other pests, in section 51;
    A program for extermination must be in place for enclosed sites.

    toilets, in section 51;
    At least one toilet must be available.
The specific requirements are:
    abrasive blasting, in section 57;
      Composition and toxicity of the dust must be evaluated and the amount in the breathing must be below the PEL's.

      Personal protective equipment such as aprons, gloves, and shoes is covered in paragraph (5).

      Silica, respirator and dust-filter mask use are described in paragraph (5).

    open surface tanks, mechanical and vapor degreasing operations, in section 57;
      The hazard potential must be determined and ventilation/exhaust or other control means must be used.

      Rescue procedures must include at least one standby employee.

    grinding and polishing, in section 57;
      The types of wheels, discs and belts and the exhaust systems are located in paragraph (g).

    lasers, microwaves and other non-ionizing radiation, in section 54;
      Qualified, trained operators may use laser equipment. Where the equipment is in use signs must be posted. Laser beams shall not be directed at anyone.

    lead, in section 62;
      Before the start of each project, a written plan following the standard must be developed.

      Exposure assessment is the level of lead to which an employee would have been exposed had he/she not been wearing a respirator. This assessment must be done initially and when there is a change in the working conditions. Employees must be informed on writing, of the results within 5 day.

      8 hour average exposure must not exceed 50 micrograms per cubic meter.

      Medical surveillance is in paragraph (j) and applies to employees exposed at or above the action level for more than 30 days in any 12 consecutive months.
