PART 1910 Occupational Safety and Health Standards |
|
|
"Right-To-Know" |
|
|
The Occupational Safety and Health Administration (OSHA) Federal Hazard Communication Standard 29 CFR 1910.1200 has become known as the "Right-To-Know" law.
This standard gives both employers and employees a right-to-know about the hazardous chemicals they use in the workplace. It is designed to reduce the incidence of chemical
source injury and illness in the workplace. |

Accident Prevention Signs |
|
|
The American National Standards Institute (ANSI Z35.1 - 1972) and the Occupational Safety and Health Administration (OSHA 190.125) Specifications for Accident Prevention
Signs require the use of safety signs to indicate and define specific hazards that, without identification, may lead to accidental injury to workers and/or the public or property damage.

Lockout / Tagout Standards |
|
|
OSHA's Lockout / Tagout standard (29CFR 1910.47) requires that all energy sources be turned off and "locked" out while machines are being serviced and maintained. In addition, Tagout
devices, including their means of attachment, shall be substantial enough to prevent inadvertent or accidental removal.
Tagout device attachment means shall be of non-reusable type, attachable by hand, self-locking, and non-releasable, with a minimum strength of no less than 50 pounds, and having the
general design and basic characteristics of being at least equivalent to a one-piece, all-environmental-tolerant nylon cable tie.

ANSI Standard A13.1-1981 |
|
|
The ANSI Standard for pipe identification is a widely used guideline in determining pipe identification requirements. The purpose of the standard is to "assist in identification of
hazardous materials conveyed in piping systems and their hazards when released in the environment." Pipes are defined as "conduits for the transport of gases, liquids, semi-liquids or fine particulate dust." |
