Safety and health signage

3A
Divulgation

Whenever necessary, the employer must take the necessary measures to ensure that there is a signage in the workplace to inform or warn workers of certain risks, prohibitions or obligations on ​​safety and health.

The signage used as Security Technique can be classified according to the sense by which it is perceived in: Optics, Acoustics, Olfactory, Tactile.

BASIC RULES

  1. Choose the signal type (luminous, acoustic, panel-shaped, gestural or verbal) and its quantity considering: the characteristics of the signal; the risks to be indicated; the extent of the area of ​​work to be covered and the number of workers to whom it is addressed.Also, the Emergency Plan must be considered.
  2. The signage should not be considered as a substitute measure for workers’ training and information on working occupational safety and health nor for technical and organizational measures of collective protection.
  3. Observe all safety signs used in the workplace.
  4. The colours that are part of the safety signage are: red (prohibition sign, alarm danger, fire-fighting material and equipment); yellow ororange yellow (warning sign); blue(mandatory sign) and green (rescue or SOS sign, security situation). The contrast colour that frames or alternates with the security colour will be white, except for the yellow that will be attached to the black.
  5. Signage intended to warn workers about the presence of a risk, or to remind them of a prohibition or obligation, will be done by means of panel signals. These will be made from a material that withstands the action and effects of the weather and its dimensions will guarantee its good understanding and visibility.
  6. Use the panels as indicated by the legislation: warning (triangular shape, black pictogram on yellow background and black edges); prohibition (round shape, black pictogram on white background, edges and cross band, red from left to right); mandatory (round shape, white pictogram on a blue background); firefighting equipment (rectangular or square shape, white pictogram on a red background); rescue or SOS (rectangular or square shape, white pictogram on green background).
  7. Install the signals in an appropriate position in relation to the visual angle. The emplacement must be accessible and well lit.
  8. The light signals should be clearly perceived, and the flashing light will indicate, in relation to the continuous light, a greater danger.
  9. The acoustic signal must have a sound level higher than the ambient noise level, so that it is clearly audible. Those that are intermittent will indicate a greater danger; however, the sound of an evacuation signal must always be continuous.
  10. Indicate slopes or other obstacles that cause risks of falls of people, shocks or blows with information panels or by alternating yellow and black stripes.
  11. Periodically check the correct functioning of the acoustic and luminous signals.
  12. Clearly delimit traffic routes for vehicles by continuous stripes of a visible colour, preferably white or yellow, considering the colour of the ground.
  13. Make gestural safety signs that are easy to carry out and understand. The person in charge of issuing the signals must be able to visually follow the operations and must dedicate himself/herself exclusively to directing the manoeuvre and safety of the workers in the immediate areas
