What can be identified as a possible ignition source in a possible hazardous environment?

EN 1127-1:2012 lists 13 ignition sources in a row like mechanical, open fire, electrical, temperature, etc.

The real matter here: what is that/are these on site? Ok.s are electrical equipments, mechanical installations, etc - most of them you can get certified from the market. But what else?:

• forklift's forks,
• tools,
• safety helmet,
• failure in the windows,
• etc...

How do you protect your Ex environment against any possible ignition sources?

EN 1117-1:2012 is for whom?!

First of all it is for Ex industry owners in general. You may invite anyone come to site and do inspection, but at the end of the day the responsibility is in his/her hands to show up proof of evidence of Ex safe functioning.

Pls note: EN 1127-1 has been fully adopted into ISO 80079-36.

But let me go back to the listed items:

• forklift's forks - you may use a special condom to pull over and use it - your only task: to check it prior to use - education is mandatory
• tools - no certification requested but manufacturer's manual shall be followed and considered - education is mandatory

• safety helmet - PPE (there shall be a separate post about) but even if being no ignition source is confirmed by manufacturer, it is the user's responsibility to follow and document it accordingly - education is mandatory
• failure in the windows - is it that much important? Think of Robinson Crusoe - he was able to ignite fire with his glasses on the no-name island - why not in a possible hazardous environment...

The fight against possible ignition sources like above shall be a daily task of one or more (in my understanding: all) being responsible for site Ex safety... BUT therefore an understanding of Ex is mandatory input...

Minimum competencies are fully described in IEC 60079-14/-17 and -19. InHouse Competency System shall focus on those competencies highlighted there.
