Construction site safety audit checklist: sources and guidance

A walk-through audit form for US construction sites. Employer safety programs provide for frequent and regular inspections of job sites, materials and equipment by competent persons [21], and equipment found out of compliance is tagged, locked out or removed [23].

How often: Frequent and regular, as set by your organization; the standard names no interval for a whole-site audit. Some items have their own timing: excavations daily before work, scaffolds before each shift and first aid kits at least weekly.[21][59][36][39]

Purpose

Use this construction site safety audit checklist to walk a site and record what you find. OSHA's construction standard expects each employer's safety program to provide for frequent and regular inspections of job sites, materials and equipment by competent persons [21]. This form turns that duty into specific checks drawn from the construction rules that apply on most sites: housekeeping, fire protection, first aid, fall protection, ladders, excavations, electrical safety, personal protective equipment and equipment. Every check names the clause it comes from.

Who should use it

A competent person designated by the employer: someone capable of identifying existing and predictable hazards [28] who has authority to take prompt corrective measures [29]. Superintendents, safety managers and general contractors auditing subcontractor areas can all use it.

How often

The standard asks for frequent and regular inspections [21] but does not set an interval for a whole-site audit, so your organization sets one. Some checks have their own timing: a competent person inspects excavations before the start of work and as needed during the shift [59], scaffolds are inspected before each work shift [36], and first aid kits are checked at least weekly on each job [39].

How to use this checklist

  1. Record the trades and activities under way, then walk the whole site, including upper floors, roofs and excavations.
  2. Answer each check for what you see today. Mark N/A for activities not on site.
  3. Stop and correct serious hazards on the spot where you have the authority to do so.
  4. List every hazard, its location, the corrective action and who owns it in the findings section, and follow up until closed.

Four checks are critical. Equipment that does not comply is tagged, locked out or removed [23]; defective portable ladders are withdrawn from service until repaired [8]; each worker on a walking or working surface with an unprotected side or edge 6 feet or more above a lower level is protected [46]; and when there are signs of a possible cave-in or hazardous atmosphere, exposed workers are removed until precautions are taken [60]. The excavation section records what was seen and what was done as two separate answers, so a No on the critical check always means workers were left exposed.

What the rules say

  • Housekeeping: scrap lumber with protruding nails and other debris is kept cleared from work areas, passageways and stairs [25], and combustible scrap is removed at regular intervals [26].
  • Fire protection: at least one 2A-rated extinguisher for each 3,000 square feet [14], no more than 100 feet of travel to the nearest one [15], and one on each floor [16]. Alarm codes and reporting instructions are posted at phones and employee entrances [20].
  • First aid: supplies are easily accessible [38]; emergency numbers are posted where 911 is not available [41].
  • Falls: unprotected sides and edges 6 feet (1.8 m) or more above a lower level are protected [46]; hole covers are secured [51] and marked [52].
  • Ladders: side rails extend at least 3 feet (0.9 m) above the upper landing [3], or, only when the ladder is too short for that, the ladder is secured at its top [4] and a grab rail is provided [5], and ladders are inspected by a competent person periodically and after any event that could affect safe use [7].
  • Excavations: workers are protected from cave-ins by an adequate protective system [61], and spoil is kept at least 2 feet (0.61 m) from the edge or held back [58].
  • Electrical: GFCIs or an assured equipment grounding conductor program protect workers [32], and worn or frayed cords are not used [35].

What this checklist does not cover

  • Detailed inspections that have their own checklists, such as scaffolds, cranes, aerial lifts, heavy equipment and personal fall arrest equipment.
  • Soil classification and design of excavation protective systems.
  • Health hazards that need exposure monitoring, such as silica, noise, lead and asbestos.
  • Hazard communication, confined spaces, steel erection, demolition and hot work permits.
  • Written safety programs and training records, which this audit does not review.
  • Rules of State Plan states that differ from federal OSHA.

Questions

How often should a construction site be inspected?

Frequently and regularly, by competent persons the employer designates [21]. The rule gives no fixed interval for a whole-site inspection. Specific items have their own timing, such as excavations before the start of work each day [59] and scaffolds before each work shift [36].

Who can conduct a construction site safety audit?

The inspections are made by competent persons designated by the employer [21]. A competent person can identify existing and predictable hazards [28] and has authorization to take prompt corrective measures to eliminate them [29].

What happens when the audit finds unsafe equipment?

Using machinery, tools, materials or equipment that do not comply with the construction rules is prohibited [22]. The item is tagged as unsafe, its controls are locked, or it is physically removed from its place of operation [23].

How many fire extinguishers does a construction site need?

At least one extinguisher rated 2A or more for each 3,000 square feet of protected building area [14], with no point more than 100 feet from the nearest one [15], and at least one on each floor [16]. Where more than 5 gallons of flammable or combustible liquids are used, a 10B-rated extinguisher is within 50 feet [18].

When does a trench need a ladder or a protective system?

Trenches 4 feet (1.22 m) or more deep have a stairway, ladder, ramp or other safe means of egress [56] within 25 feet (7.62 m) of lateral travel [57]. Workers in an excavation are protected from cave-ins by a protective system [61] unless the excavation is less than 5 feet (1.52 m) deep and a competent person finds no sign of a potential cave-in [63], or it is made entirely in stable rock [62].

Are GFCIs required on construction sites?

The employer uses either ground fault circuit interrupters or an assured equipment grounding conductor program [32]. GFCI protection applies to 120-volt, single-phase, 15- and 20-ampere receptacle outlets that are not part of the building's permanent wiring [33].
