Adequate illumination is crucial for safety on construction sites 3, 10. Here's what you need to know:

  • General Illumination: Construction areas, aisles, stairs, ramps, corridors, offices, shops, and storage areas must be adequately lighted with natural or artificial illumination when work is in progress [1].
  • Minimum Illumination: Areas accessible to employees must be lighted to not less than the minimum illumination intensities [2].
  • Night Work & Poor Visibility: When working at night or in conditions of poor visibility, power lines must be illuminated or another means of identifying the location of the lines must be used [3]. A safe path of travel must be identified and used [3].
  • Mobile Equipment: Powered mobile equipment operated during hours of darkness or when visibility is poor must be equipped with lights that illuminate the direction of travel, the working area, and the control panel [4].
  • Emergency Lighting: Emergency lighting must be available at a work site if workers are in danger if the normal lighting system fails [5]. This lighting should allow workers to leave the site safely, start emergency shutdown procedures and restore normal lighting [5].
  • Urban Areas: When operating in dark locations, turn on the work light. If necessary, use additional lighting devices to make the work areas bright enough to operate 7, 8, 9, 15.
  • Portable Luminaries: Ensure electrical cords and fittings are approved for the intended use and properly maintained [6].
  • Luminaire Safety: Ensure that a luminaire that is located at a height of less than 2.1 meters above a working or walking surface is protected against physical or mechanical damage by installation of a safeguard or the location of the luminaire [6].

It's also important to stop work if you have poor or limited visibility due to darkness, fog, rain, or snow 7, 8, 9, 15, 17.

Equipment traveling on a construction site with a load is governed by 1926.1408, 1926.1409 or 1926.1410, whichever is appropriate, and 1926.1417(u). - (b) The employer must ensure that: - (1) The boom/mast and boom/mast support system are lowered sufficiently to meet the requirements of this paragraph. - (2) The clearances specified in Table T of this section are maintained. - (3) The effects of speed and terrain on equipment movement (including movement of the boom/mast) are considered so that those effects do not cause the minimum clearance distances specified in Table T of this section to be breached. - (4) Dedicated spotter. If any part of the equipment while traveling will get closer than 20 feet to the power line, the employer must ensure that a dedicated spotter who is in continuous contact with the driver/operator is used. The dedicated spotter must: - (i) Be positioned to effectively gauge the clearance distance. - (ii) Where necessary, use equipment that enables the dedicated spotter to communicate directly with the operator. - (iii) Give timely information to the operator so that the required clearance distance can be maintained. - (5) Additional precautions for traveling in poor visibility. When traveling at night, or in conditions of poor visibility, in addition to the measures specified in paragraphs (b)(1) through (4) of this section, the employer must ensure that: - (i) The power lines are illuminated or another means of identifying the location of the lines is used. - (ii) A safe path of travel is identified and used.
