Unprotected Skylights: OSHA Regulations, Guidelines and Solutions
Unprotected skylights create serious fall hazards on rooftops across commercial and industrial sites. A skylight opening can look like a solid part of the roof, but many are not built to support a person's weight. Without proper safeguards, a single misstep near a skylight can lead to a life-threatening fall.
The Occupational Safety and Health Administration (OSHA) enforces strict rules to prevent these incidents, and other regulatory bodies hold similar standards. Yet many rooftops still fall short of compliance, leaving workers exposed to unnecessary risk.
This article covers what makes a skylight unprotected, where these gaps fail compliance, OSHA's recommendations for safer elevated work zones, and how Safety Rail Source® helps facilities close these safety gaps.
What are Unprotected Skylights?
An unprotected skylight is a roof opening without a guardrail, screen or cover strong enough to prevent a fall. Skylights are often made of glass, plastic or other lightweight materials that cannot support a person's weight. Without a physical barrier in place, workers walking or working near the opening face a serious fall hazard.
An opening can be considered unprotected in several common scenarios, including:
- No guardrail, screen or cover installed around or over the opening
- A cover in place that is not rated to hold at least twice the maximum intended load
- A screen or cover that has been removed or shifted out of place and not reinstalled
- Damaged or deteriorated glazing that has weakened over time, sometimes worsened by environmental factors that contribute to falls
- A guardrail positioned too far from the opening to prevent a worker from stepping through
- No warning markings or signage to alert workers of the hazard's location
How Unprotected Sites Fail OSHA 1910.28 Compliance
OSHA requires employers to protect workers from falling through any hole, including skylights. Despite this clear standard, many facilities fall short of compliance in the same recurring ways.
The most common skylight-related violations include:
- No fall protection installed. The site has no guardrail, cover or personal fall arrest system around a skylight or roof opening, leaving it fully exposed.
- Undersized or unrated covers. A cover is in place but cannot support at least twice the maximum intended load, so it fails under a worker's weight.
- Improperly secured covers. Unfastened covers may shift or slide out of position.
- Guardrails installed too far from the hazard. A guardrail exists on the roof but does not surround the opening closely enough to stop a worker from stepping through it.
- Lack of hazard identification. Openings are not marked, painted or labeled to alert workers of their location, especially during low-visibility conditions.
- Inconsistent maintenance. Covers, screens or guardrails were installed correctly at one point but have since been damaged, removed or not reinstalled after roof work.
OSHA Recommendations for Safeguarding Skylights
OSHA 1910.28 and OSHA 1910.29 sets the specific criteria that fall protection systems must meet to safeguard skylights and other roof openings. This includes cover strength, guardrail dimensions and installation requirements. Employers must meet these standards regardless of whether they use a cover, screen or guardrail system. For more details about OSHA compliance requirements for skylights, check out our OSHA FAQ.
Below, we outline some of the specific skylight safety requirements that OSHA specifies:
- Cover Strength. Any cover placed over a skylight or hole must support at least twice the maximum intended load that could be placed on it at any time.
- Cover Security. Covers must be secured to prevent displacement, so wind, foot traffic or debris cannot shift them out of place.
- Top Rail Height. Guardrail top rails must sit between 39 and 45 inches above the walking-working surface.
- Top Rail Strength. Top rails must withstand at least 200 pounds of force applied in a downward or outward direction.
- Midrail Requirement. A midrail, screen, mesh or equivalent barrier is required midway between the top rail and the walking-working surface when no wall or parapet is present.
- Guardrail Placement. Guardrails must be positioned close enough to the opening to prevent a worker from stepping through the gap between the rail and the hazard.
How Safety Rail Source® Reinforces Skylight Safety
SRS offers a range of OSHA compliant products designed to help facilities maintain skylight safety and close the gaps outlined above. Our product lineup falls into several categories, so facilities managers can choose the solution that fits their rooftop:
Skylight Screens
- NextGen Skylight Safety-Screens™. These screens sit directly over the skylight and meet a 200 to 400-pound-load requirement. Meaning, a worker who steps on the opening is held safely above it instead of falling through.
Guardrail Systems
- NextGen 3000™ Universal Guardrail. This non-penetrating, modular guardrail surrounds skylights and other roof hazards with a physical barrier. This keeps workers from getting close enough to fall through the opening.
- Kee Guard® Skylight Railing. Counterbalance weights hold this railing in place around a skylight without penetrating the roof. This forms a perimeter that stops workers before they reach the hazard.
- Kee Dome® Skylight Railing. Built with PVC bases and posts, this railing wraps around domed and barrel vault skylights to block access to the opening while leaving the roof membrane undisturbed.
- Roof Hatch Railing. Since roof hatches often sit near skylights on the same rooftop, this railing closes off an additional fall hazard that workers may encounter while moving toward a skylight.
Warning Line Systems:
- NextGen Warning Lines™. This rope and stanchion system marks a boundary around skylights on low-slope roofs, alerting workers to the hazard before they get close enough to be at risk.
Personal Fall Arrest Systems:
- Mobile Fall Protection Penetrators. If a connected worker falls near a skylight, this system releases spikes into the roof to arrest the fall before the worker reaches the opening below.
- Roof Anchors. Anchors such as the Hippo Anchor™ give workers a secure tie-off point near skylights, so a harness and lanyard can stop a fall before it reaches the opening.
- Harnesses and Lanyards. Paired with a roof anchor, these connective devices keep a worker tethered while working near a skylight. This limits how far they can fall if they lose their footing.
Beyond skylight protection, SRS manufactures a full range of rooftop safety products. We offer a line of high-quality roof edge guardrails, roof and floor hatch solutions, and crossover stairways, platforms and ramps that help workers navigate rooftop obstacles safely. We also offer custom design, CAD drawings and installation services for facilities with unique layouts. Browse our full product catalog to find the right fall protection solution for your site.
