PowerPoint 14: Warning signs PowerPoint presentation 1. Health and safety in building services engineering
1.13 Safety Signs<br>
02
Objectives By the end of the session learners should be able to:
describe the different types of safety sign found in the construction industry
identify the symbols for hazardous waste
understand the meaning of each pictogram in the Classification, Labelling and Packaging (CLP) Regulation and where each might be encountered.<br>
03
Safety signs A building site is a very dangerous place, full of potential hazards. It is very important that you should always try and mitigate against these hazards. Warning signs on site help to warn people of possible dangers.
There are four main types of safety sign:
prohibition signs
warning signs
mandatory signs
emergency/information signs.<br>
04
The four colours of safety signs<br>
05
Prohibition signs Prohibition signs advise what is not allowed in a particular area. Do not drink
Do not touch
No naked flames
No access for pedestrians<br>
06
Warning signs Warning signs identify the potential dangers in a particular area. Corrosive material
Danger, electricity
Flammable materials
Trip hazard<br>
07
Mandatory signs Mandatory signs identify what must be done by all people when on a construction site. Safety boots must be worn
Eye protection must be worn
Pedestrians walk this way
Hard hats must be worn<br>

Emergency/information signs Emergency/information signs show information relating to health and safety on a construction site. Emergency exit route
Emergency eye wash
First aid

CLP pictograms The Classification, Labelling and Packaging (CLP) Regulation lists a series of pictogram labels that identify the type of substance within a sealed container that may pose a risk to health and safety.
Hazard pictograms are universally understood warning symbols intended to provide information about the damage a particular substance or mixture can cause to health or the environment.
Post-Brexit, the CLP Regulation is now known as the GB CLP Regulation but still uses the United Nations Globally Harmonised System of hazard symbols.<br>
