Concrete and Masonry Construction Safety

For workers on concrete and masonry crews: spot impalement, bucket and post-tensioning hazards, use concrete equipment safely, work around formwork and shoring, stay clear of precast and lift-slab loads, and respect the masonry limited access zone.

Based on OSHA 29 CFR 1926 Subpart Q (1926.700–1926.706, concrete and masonry construction) · about 7 min read

Everyday concrete hazards

Hazards on a pour day

These rules apply on most concrete jobs.

Impalement
All protruding reinforcing steel that you could fall onto or into must be guarded to eliminate the hazard of impalement.
Working under buckets
No one may work under a concrete bucket while it is being raised or lowered into position. As far as practical, the bucket is routed so that no one, or the fewest people, are exposed if it falls.
Riding buckets
No employee may ride a concrete bucket. Ever.
Post-tensioning
During tensioning, no one except those essential to the operation may be behind the jack. Signs and barriers limit access to the post-tensioning area.
Head and face protection
You may not apply a cement, sand and water mixture through a pneumatic hose unless you wear protective head and face equipment.
Construction loads
No construction loads go on a concrete structure unless the employer determines, based on information from a person qualified in structural design, that it can support them.

Equipment and lockout

Safeguards your equipment must have

Before you use a piece of equipment, check that its required safeguard is there and working.

Good practice: if a safeguard is missing, defeated or broken, do not use the equipment. Tell your supervisor.

Equipment and lockout

Lock it out before you fix it or climb in

Maintenance and repair

You may not do maintenance or repair on equipment such as compressors, mixers, screens or pumps, where it could start up unexpectedly and hurt you, unless all potentially hazardous energy sources are locked out and tagged.

Tags must read Do Not Start or similar language.

Bulk cement bins and silos

You may not enter a bulk cement storage bin, container or silo unless the ejection system has been shut down, locked out and tagged.

Reference: 29 CFR 1926.702(j)(1) · 29 CFR 1926.702(j)(2) · 29 CFR 1926.702(a)(2)

Formwork and shoring

Check the shoring before, during and after the pour

Formwork must be built and maintained to carry, without failing, all the vertical and lateral loads that can reasonably be expected. Drawings or plans for the jack layout, formwork and shoring, working decks and scaffolds, including all revisions, must be available at the jobsite.

When shoring is inspected

What a sound shore looks like

Good practice: during a pour, watch for sagging, bulging, cracking or creaking forms and shores. Get people clear and tell your supervisor right away.

Reference: 29 CFR 1926.703(a)(1) · 29 CFR 1926.703(a)(2) · 29 CFR 1926.703(b)(1) · 29 CFR 1926.703(b)(2) · 29 CFR 1926.703(b)(3) · 29 CFR 1926.703(b)(4) · 29 CFR 1926.703(b)(5) · 29 CFR 1926.703(b)(6) · 29 CFR 1926.703(b)(9)

Formwork and shoring

Rebar, wire mesh and stripping forms

Rebar and wire mesh

When forms can come down

Forms and shores (except for slabs on grade and slip forms) stay up until the employer determines the concrete is strong enough to support its own weight and the loads on it. That decision must be based on one of these:

Reshoring goes in as original forms and shores are removed whenever the concrete must carry loads beyond its capacity. Reshores stay until the concrete has adequate strength for its weight and all loads on it.

Your part: do not strip forms or pull shores because the concrete "looks hard." Wait for the go-ahead from the person who made the determination.

Precast and lift-slab

Stay out from under lifted members and slabs

Precast and tilt-up

Lift-slab jacking

In lift-slab construction, slabs are cast at ground level and jacked into place.

Reference: 29 CFR 1926.704(a) · 29 CFR 1926.704(e) · 29 CFR 1926.705(k)(1) · 29 CFR 1926.705(k)(2) · 29 CFR 1926.705(k)(3) · 29 CFR 1926.700(b)(3)

Masonry walls

The limited access zone and wall bracing

A limited access zone is an area alongside a masonry wall under construction, clearly marked to limit who can enter. One must be set up whenever a masonry wall is being built.

WhenSet up before construction of the wall starts.
How wideThe height of the wall to be built plus four feet, along the entire length of the wall.
Which sideThe side of the wall that will be unscaffolded.
Who entersOnly employees actively engaged in building the wall. No one else.

How long it stays

Bracing walls over eight feet

All masonry walls over eight feet high must be adequately braced to prevent overturning and collapse, unless the wall is already adequately supported. Bracing stays in place until the permanent supporting elements of the structure are in place.

Example: a block wall that will be 12 feet tall needs a zone 16 feet wide on the unscaffolded side, running the full length of the wall.

Fact-checked against the regulation text on October 09, 2026. This certificate records completion of awareness training based on OSHA 29 CFR 1926.700, 1926.701, 1926.702, 1926.703, 1926.704, 1926.705 and 1926.706 (Subpart Q, concrete and masonry construction). It is not an OSHA card or license. Subpart Q has no training requirement of its own, and this certificate does not by itself meet the employer's training duty under 29 CFR 1926.21(b)(2). Your employer must still instruct each employee in the recognition and avoidance of unsafe conditions and the regulations applicable to their work environment to control or eliminate any hazards or other exposure to illness or injury.

This guide explains the rule in plain words. Always read the regulation itself and your employer's site-specific procedures.
