What is HSG38?

What is HSG38?

Below is a table that has been reproduced from HSE document HSG38 (Lighting at Work). It gives the recommended minimum lighting levels for different types of work activity and location. Activity. Typical Location.

What is lighting in health and safety?

Lighting and performance Poor lighting is a safety hazard – misjudgement of the position, shape or speed of an object can lead to accidents and injury. The extent to which various lighting levels affect workers’ performance depends on the proportion of the visual component within the visual task.

What Lux should office lighting be?

Key principles in lighting A process control room should be lit at an illuminance of 300 lux, a corridor or walkway may only require 50 lux, whilst studying an engineering drawing may require 750 lux (see HSG38 Lighting at Work).

What is the minimum light intensity at the workplace?

The minimum illumination required for general lighting in general construction areas, warehouses and workplace hallways and corridors is five candle-feet. Physical plants, shops, machining areas, equipment and work rooms is 10 candle-feet, and office areas require at least 30 candle-feet of illumination.

Is emergency lighting a legal requirement HSE?

Where daylight provides adequate lighting, no further action is required. Where emergency routes need artificial light, provide emergency lighting that comes on if the primary lighting fails e.g. battery or emergency generator-powered lighting.

What are the key safety issues with lighting?

Poor lighting can affect the quality of work, particularly in a situation where precision is required, and overall productivity. Poor lighting can be a health hazard – too much or too little light strains eyes and may cause eye irritation and headaches.

What is a good Lux level?

For precision & detailed works, the level of light may range between 1500 to 2000 lux. In homes- The recommended illumination levels for homes is often 150 lux. The living and dining rooms may work pretty well with about 25 to 50 lux.

What is emergency lighting used for?

1) Emergency Escape Lighting is the lighting which provides sufficient illumination so that all occupants can evacuate in the event of an emergency situation, or attempt to terminate any potentially dangerous processes before evacuation.

What is lux level?

The standard unit for measuring the light level intensity is termed as LUX level. It is also known as illumination or illuminance. It calculates the intensity of light the falls on the surface like – floors or walls in the lighting design.

What’s the difference between lumens and lux?

1 lux equals 1 Lumen/m2, in other words – light intensity in a specific area. Lux is used to measure the amount of light output in a given area. One lux is equal to one lumen per square meter. It enables us to measure the total “amount” of visible light present and the intensity of the illumination on a surface.

What is OSHA standards for lighting?

General Lighting Requirements First-aid stations, offices, and infirmaries: 30 foot-candles. General construction plants and shops: 10 foot-candles. General construction area: 5 foot-candles. Warehouses, walkways, corridors, exits, and other indoor spaces: 5 foot-candles.

What are the requirements for emergency lighting?

The emergency lighting must be arranged to provide initial illumination of not less than an average of one foot-candle (10.8-lux) and a minimum at any point of 0.1-foot-candle (1.1-lux) measured along the path of egress at floor level.

What is lux calculation?

The Calculation of LUX level in a room The LUX level in a room is calculated from the following formula. E(LUX) = F(lm) x UF x MF / A. Where. E is the the LUX level achieved. F is the average lumens value form the light source.

What is HSG 38 lighting at work?
