Commonsense Code Changes Keep Construction Sites Fire Safe

In January 2019, the governmental voting body of the International Code Council (ICC) approved changes to the International Fire Code (IFC), 2021 edition, that will aid in safeguarding construction sites. Although construction fires—including buildings under major renovation and demolition—account for about 1.7 percent of the nation’s annual structure fire responses and about 3.2 percent of annual fire losses,the estimated economic impact is $310 million per year.(1) Construction site fires affect not only the building under construction, they can cause a disproportionate negative effect, including the following:

  • Project abandonment.
  • Economic development impact.
  • Financial loss and increased insurance costs.
  • Environmental damages.
  • Fire Service depletion for other incidents.
  • Water supplies.
  • Traffic and area interruptions.

Daily Fire Safety Inspections

The most impactful change regarding construction fire safety is in the IFC’s Chapter 33, requiring the construction “site safety director” (formerly named the “fire prevention program superintendent”) to conduct daily fire safety inspections at the project site. These daily inspections must include the exterior and interior of buildings under construction until the certificate of occupancy is issued.

Daily inspections must be documented, and records must be made available immediately on request of the fire official. Failure toconduct or document daily inspections can result in a violation. On the third offense, the fire official can issue a “stop work” order until the fire code official receives “satisfactory assurances” of future compliance.

Daily Inspection Requirements

The following are requirements of these daily fire inspections:

  • Inspect hot work areas and ensure hot work is being conducted according to the hot work plan.
  • Inspect all temporary heating equipment, ensuring it is away from combustibles.
  • Ensure combustible trash and debris are removed from the nonwork areas.
  • Ensure temporary wiring does not have exposed conductors.
  • Ensure flammable liquids and hazardous materials are being stored properly in approved locations.
  • Inspect fire access roads to confirm they are free of obstructions.
  • Confirm fire hydrants are unobstructed and “clearly visible.”
  • Ensure standpipes are in service and go up with the building within one floor of the highest construction level.
  • Ensure portable fire extinguishers are in service and properly spaced.

One of the code changes also relocates Section 3308 in Owner’s Responsibility for Fire Protection to Section 3303 so that these important requirements are in the front of Chapter 33 in Fire Safety During Construction and Demolition.

Fire Watch Requirements

The 2021 IFC will make a fire watch mandatory for buildings more than 40 feet in height or with an aggregate area exceeding 50,000 square feet. It was felt that “these buildings are large enough to create a significant loss to the community, endanger firefighters, and consume resources…if the building burns.”2

Another change allows fire watch personnel to also serve as security. Fire watch personnel must be trained in the use of portable fire extinguishers and fire reporting. The fire watch must have at least one means to notify the fire department. Fire watch personnel must also keep a record of all time periods of duty including a log of all patrols and the times and locations that buildings were entered and inspected.

Cooking Separation Requirement

According to the National Fire Protection Association (NFPA), the leading cause of construction fires is cooking. Twenty-seven percent of all construction fires were caused by cooking equipment. (1) The designated cooking area must be at least 10 feet from combustible materials with signage indicating a “designated cooking area.” Cooking outside this approved area is prohibited.

Site Safety Plan Requirements

A “site safety plan” will be required and must be submitted prior to issuance of a building permit. New code sections outline site safety plan required content as follows:

  • Name and contact information of the site safety director.
  • Documentation of training.
  • Procedures for emergency notification.
  • Fire department vehicle access.
  • Location of fire protection equipment and systems.
  • Smoking and cooking policy, including designated areas to be used.
  • The location and safety considerations for temporary heating equipment.
  • Hot work permit plan.
  • Plans for control of combustible waste material.
  • Locations and storage methods of flammable and combustible liquids and other hazardous materials.
  • Provisions for site security.
  • Changes that affect the site safety plan.
  • Other site-specific information required by the fire code official.

Site Safety Director Responsibilities

According to the 2021 IFC, the site safety director must have qualifications “specific to their roles and responsibilities.” The training and qualifications must be made available to the fire official on request. No specific training or qualifications are enumerated in the code for the position of site safety director.

Duties of the site safety director include ensuring compliance with the site safety plan, being responsible for the guard service, training of fire watch personnel, ensuring all fire protection equipment is operational, ensuring hot work procedures are followed, planning for all system impairments, and maintaining all required records.

Moving Forward

Although these code changes are a step in the right direction, unless fire departments actively enforce them, construction fires will continue. The primary problem is that inspecting construction sites is not a traditional role for the fire service. Annual inspections are triggered by issuance of a certificate of occupancy.

Building inspectors who actively inspect during construction are looking at approved plans and matching them against the “as-built” structure. Fire safety inspections are not a traditional function for building inspectors; it is this “gap” in responsibility that has led to unsafe practices and subsequent construction fires that make the news more often than they should.
