Safety mark
The affixing of safety signs (according to DIN safety signs ), the safety signs , serves the prevention of accidents and health protection in particular and safety in general, especially at the workplace ( occupational health and safety ).
Basics
On the one hand, safety signs are intended to inform the viewer about
- Dangers that arise from certain facts, such as the risk of falling, crushing, the presence of dangerous substances, e.g. B. toxic or corrosive substances , radioactive substances , or from hazardous plants, e.g. B. Systems with high electrical voltage , laser beams etc. ( warning signs )
- the need to refrain from certain behavior ( prohibition sign ) in order to avoid accidents, such as smoking or handling other open flames due to the actual presence of explosive gases, dusts and vapors, e.g. B. near petrol pumps ,
- the need to show certain behavior ( mandatory signs ) in order to avoid accidents or to mitigate their consequences, e.g. B. the requirement to wear safety helmets in certain areas , or to avoid damage to health , z. B. the requirement to wear hearing protection or a respirator in a certain area,
on the other hand, they should point to
- Paths to rescue ( emergency signs ) and escape from danger areas, e.g. B. on escape routes , rescue routes and emergency exits in the event of fire ( fire protection signs ) , or protected areas, e.g. B. Shelters in tunnels or in the event of a tornado etc.
- Rescue aids, such as supplies of medical supplies for first aid , eye showers , oxygen masks, etc. (rescue, first aid).
Safety signs are often designed as pictograms and are therefore self-explanatory. In addition, their importance is often explained to all employees of a company or facility in written fire protection regulations and also to visitors and guests through notices.
Security codes are beyond for drawing escape and rescue plans , from fire department plans and fire brigade route maps used.

Legislation
In Germany, the safety marking is regulated in the trade association regulations , and can be found in particular in DGUV information 211-041 and the DIN standard DIN 4844-1, the registration of standardized symbols in DIN 4844-2. The new symbols according to the DIN EN ISO 7010 standard are internationally and European and were adopted in the technical rule for workplaces ASR A1.3 on February 27, 2013 .
ASR A1.3 and DIN EN ISO 7010 define code letters for the various categories of safety signs:
- P = prohibition sign
- W = warning sign
- M = mandatory sign
- E = escape sign
- F = fire protection symbol
- S = additional character
- H = reference symbol
- C = combination sign
Each standardized safety label can be identified by the code letter and a three-digit number.
Where safety signs are to be affixed is regulated in detail in the workplace ordinance and many special regulations, especially on fire protection .
Security colors and geometric shape
ASR A1.3 defines the following shapes and colors for the safety signs:
