Identifies information about practices or circumstances that 

can cause an explosion in a hazardous environment, 

which may lead to personal injury or death, property 

damage, or economic loss.

 

 

Identifies information that is critical for successful 

application and understanding of the product.

 

 

Identifies information about practices or circumstances that 

can lead to personal injury or death, property damage, or 

economic loss. Attentions help you identify a hazard, avoid 
a hazard, and recognize the consequence.

 

 

Labels may be on or inside the equipment, for example, a 

drive or motor, to alert people that dangerous voltage may 
be present.

 

 

Labels may be on or inside the equipment, for example, a

dangerous temperatures.

 

General Safety Information 

 

This application example is for advanced users and 
assumes that you are trained and experienced in safety 

system requirements.

 

 

A risk assessment should be performed to make sure all 

task and hazard combinations have been identified and 

addressed. The risk assessment may require additional 

circuitry to reduce the risk to a tolerable level. Safety 
circuits must take into consideration safety distance 

calculations which are not part of the scope of this 

document.

assessment services.
