Purpose

This standard establishes minimum requirements for materials, processes, and engineering practices for the design of ground life support ground systems and equipment for use at KSC and other installations under KSC design responsibility. Where the requirements of this standard do not meet the minimum program or project requirements, those program or project requirements shall take precedence.

Applicability

a. This standard applies to all fixed, portable, and mobile life support systems and equipment used to provide service or protection for a user who will be working in, escaping from, or resuscitating a victim physically injured within or exposed to one or more of the following environments:

(1) fuel vapors (hydrazine, monomethylhydrazine, unsymmetrical dimethylhydrazine, Aerozine 50, hydrogen);

(2) oxidizer vapors (nitrogen tetroxide, inhibited red-fuming nitric acid, hydrogen peroxide);

(3) smoke;

(4) oxygen-deficient atmospheres (nitrogen-purged areas, partial vacuum, areas containing fire-extinguishing agents such as carbon dioxide and Halon 1301);

(5) ammonia.

b. These requirements apply to new equipment that has not been verified to meet requirements of a previous revision of this standard. Equipment designed or fabricated prior to the effective date of this standard may be verified as acceptable for use against the requirements of a previous revision of this standard. Any design changes to such equipment shall meet the requirements of this revision of this standard.

National Institute for Occupational Safety and Health (NIOSH) approved equipment is exempt from the requirements of this standard.

Use of Shall, May, Should, and Will

In this standard, "shall" denotes mandatory actions (i.e., requirements) that are verified. "May" denotes discretionary privilege or permission. "Should" denotes a good practice that is recommended but is not required. "Will" denotes an expected outcome, a requirement levied by others, or a requirement that does not have mandated verification. When this standard is placed on a contract, the "will" statements in this standards manual are equivalent to "shall" statements for the purposes of the contract.
