Burns:
Burns can be caused by the uncovered parts of the applicator, such as
the guns, or by splashes of hot melt.
The hot adhesive under pressure in the nozzles can cause serious skin
injury.
Qualified personnel:
Qualified personnel are technical staff members who have acquired
sufficient knowledge in a specific field, through either training or
experience.
These personnel must be familiar with safety and accident prevention
standards, and have general knowledge of the technical aspects of the
machine.
Protective clothing:
Clothing will be compliant with EN510 and EN340 standards,
protecting against flying debris and high temperatures.
Clothing will be as tight as possible to prevent it from catching on
mobile machine parts, and the sleeves, waist, legs, etc. will be
adjustable to the size of the wearer.
Goggles and face shields:
Goggles will be compliant with the EN 166 standard, protecting against
flying debris and high temperatures.
Goggles only protect the eyes. Face shields are preferable, as they
protect the entire face.
Protective gloves:
Gloves will be compliant with EN 407 and EN 420 standards,
protecting the hands against burns caused by external, heated
substances at temperatures above 100 °C.
Elements susceptible to electrostatic discharge:
When handling equipment, avoid contact with electronic components
and metal pins on the connectors.
