A lighting risk assessment identifies areas where inadequate illumination levels create accident, eye-strain, or security risks across workplace zones. According to the National Safety Council (NSC) India, poor or inadequate lighting contributes to approximately 23% of workplace slip, trip, and fall accidents in Indian manufacturing and commercial facilities annually. IS 3646 (Code of Practice for Interior Illumination) specifies minimum lux levels for different work areas: 500 lux for fine assembly work, 300 lux for general office work, and 150 lux for corridors and warehouses—requirements routinely unmet in older Indian industrial buildings.
At a Pune auto-component manufacturing plant audited in 2023, lighting measurements revealed assembly line lux levels of 180–220 lux against an IS 3646 requirement of 500 lux. The plant had recorded 14 minor hand injuries and 6 near-miss incidents in the previous 12 months in poorly lit zones. Retrofitting with LED luminaires to achieve IS 3646 compliance cost ₹8.5 lakhs—while simultaneously reducing lighting electricity consumption by 42%, saving ₹3.2 lakhs annually. The retrofit paid for itself in 2.6 years through energy savings alone, excluding the avoided accident cost savings.
Lighting risk assessments are required under the Factories Act 1948 (Section 17—lighting) and NBC 2016 Part 8 for commercial buildings. This guide covers what assessors check, what the IS 3646 lux thresholds mean for your facility type, and what typical correction costs look like across Indian industrial and commercial contexts.
A lighting risk assessment measures lux levels across work zones and compares them against IS 3646 and NBC 2016 requirements. For a 10,000 sq.ft Indian factory or office, assessments cost ₹15,000–₹40,000. Most facilities have 3–6 non-compliant zones; LED retrofit corrections typically cost ₹5–20 lakhs and pay back in 2–4 years through energy savings.

In a lighting protection study, professionals examine the current lighting setup and assess how well it provides sufficient lighting. In order to identify areas that might need extra lighting or adjustments, they also evaluate the space’s layout and design. Moreover, they take into account outside variables that could affect the operation of the lighting system, like the climate & the surrounding area. Many essential components are included in a Lighting Risk Assessment, all of which are necessary to guarantee safety. These components consist of determining possible risks, assessing the risks, & creating a plan for risk management.
Examining the area thoroughly and determining any elements that could be dangerous are necessary steps in identifying potential hazards. This may be the result of broken wiring, insufficient lighting fixtures, or objects blocking the light source. Fire hazards, lightning strikes, electrical surges, and other external and internal dangers must all be taken into account. Assessing each potential hazard’s associated risks comes next after it has been identified.
Assessing the possibility of an incident happening as well as its possible effects is part of this. A space containing flammable materials or outdated electrical wiring, for instance, may be more likely to experience a fire hazard. Through risk assessment, organizations are able to efficiently allocate resources and set priorities for their efforts.
A thorough risk management plan is created based on the hazards that have been identified and the risks that have been assessed. The actions that will be taken to lessen or completely eradicate the risks that have been identified are described in this strategy. It could entail doing things like setting up emergency lighting, lightning rods, & surge protectors.
Regular testing and maintenance of the lighting protection system should also be included in the plan to guarantee its efficacy. Numerous possible risks and hazards may be found during a lighting risk assessment. Various conditions and settings can result in different hazards. Lightning strikes, electrical surges, and fire hazards are a few of the frequent risks and hazards connected to poor lighting.
Power fluctuations and malfunctioning electrical systems are two reasons why electrical surges can happen. They have the potential to harm electrical equipment, light fixtures, and even start fires. The safety of people & property can be ensured by identifying possible electrical surges & installing surge protectors to help prevent damage. Another major risk is being struck by lightning, particularly outside. They are dangerous to people’s lives and have the potential to seriously harm buildings and electrical systems.
To safely divert electrical charge into the ground & lower the risk of damage and injury, install lightning rods and grounding systems. Bad lighting also raises the possibility of fire. The risk of fires can be raised by hot fixtures, faulty wiring, or combustible objects near lighting sources. These risks can be reduced with the aid of routine maintenance, inspections, and compliance with fire safety codes. To address every risk and hazard that has been identified, a thorough risk management plan must be developed.
The steps that will be taken to reduce or eliminate the risks brought on by inadequate lighting should be described in this plan. Surge protector installation is one practical solution. Surge protectors guard electrical equipment and lighting fixtures against power surges & assist in controlling electrical current. They prevent damage and lower the risk of fires by serving as a barrier between the electrical source and the devices.
An all-encompassing risk management plan should also include lightning rods. They give lightning strikes a safe route to travel while directing the electrical charge into the earth. The possibility of electrical systems and structures being damaged can be greatly decreased by installing lightning rods. In order to guarantee safety during blackouts or emergencies, emergency lighting is also crucial.
It lets people move around the building safely & escape if needed by providing illumination in key areas like stairwells, exits, and evacuation routes. It’s crucial to test lighting arrestors on a regular basis to make sure the lighting protection system is operating effectively. Devices known as lighting arrestors shield electrical systems from the destructive effects of lightning strikes.
They protect equipment and buildings by safely discharging the electrical charge into the earth. Lighting arrestor routine testing facilitates the detection of system flaws or malfunctions. It guarantees the appropriate level of protection and proper operation of the lighting protection system.
Accurate evaluation of the system’s performance requires the knowledge and experience of qualified professionals, who should conduct the testing.
