7.8. General Requirements.

Lighting Levels

Illuminate facilities, accessways, and working areas as per minimum intensities specified in ANSI Workplace Lighting Standards or as stated in specific regulations like 29 CFR 1926.56 for construction sites, UFC 3-530-01 for DoD facilities, ABS guide for marine lighting, and NFPA 101 for egress and emergency lighting.
Ensure emergency lighting in construction buildings allows safe egress during power outages, with arrangements to prevent darkened areas due to single lighting unit failure.
Measure and record illumination with a calibrated light meter when minimum lighting requirements are in question.

Lighting Fixtures

Guard and secure lamps and lighting fixtures to prevent injury and accidental contact or breakage.
Install fixtures within 7 feet of working surfaces with guards or protective means, and ensure open fixtures have wire guards or other protective devices.
Maintain a minimum distance of 18 inches between lighting fixtures and overhead sprinkler systems in buildings.

Temporary Lighting

Install temporary lighting according to chapter 11 guidelines.
Ensure generator-powered portable lighting units are grounded as per manufacturer’s instructions and conduct overhead power line surveys as required.

EM 385-1-1 Paragraph 7-8.

7-8. General Requirements.

a.  Lighting Levels.  While work is in progress, facilities, accessways, working areas, roads, etc., must be illuminated to not less than the minimum intensities specified below (see table 7-1 for limited reference and requirements).  Areas not specified below must be illuminated according to the minimum intensities specified in the applicable ANSI Workplace Lighting Standards.  (7-8.a)

(1)  For construction work sites, see 29 CFR 1926.56.

(2)  Design DoD facilities, according to UFC 3-530-01.

(3)  For marine lighting, see ABS, Guide for Crew Habitability on Ships.

(4)  For illumination of means of egress and emergency lighting, see NFPA 101.

(a)  Provide emergency lighting for buildings under construction when the progress of construction or environmental conditions limits the ability of natural lighting to provide safe egress (average of 1 foot candle or 10.7 Lux) during a power outage.

(b)  The illumination must be arranged so that the failure of any single lighting unit, including the burning out of an electric bulb, will not leave any area darkened to the point of impeding the means of egress.

(5)  Take and record illumination readings, with a calibrated light meter, when the minimum lighting requirements of an area is in question.

b.  Lighting Fixtures. (7-8.b)

(1)  Guard and secure lamps and lighting fixtures to preclude injury to personnel. Light fixtures used for general illumination must be provided with protection to prevent accidental contact or breakage.

(a)  Provide lighting fixtures within 7 feet (2.1 m) of a normal working surface with suitable fixtures or lamp holder with a guard.

(b)  Open fixtures must have wire guards, lenses, tube guards and locks, or safety sockets that require force in the horizontal axis to remove the lamp, or other means to prevent damage to the bulb.

(2)  When buildings are equipped with overhead sprinkler systems, lighting fixtures must be no closer than 18 inches (45.7 cm) to an overhead sprinkler.

c.  Temporary lighting. (7-8.c)

(1)  Temporary lighting will be installed according to chapter 11.

(2)  Generator-powered portable lighting units must be grounded according to the manufacturer’s instructions.  Conduct overhead power line survey according to paragraph 7-5.
