Questions about chlorine safety

Hi, I was wondering if there are any tips from you guys about safety when using chlorine gas. I plan to do a couple projects that involve chlorine gas and I was wondering if there is anything that I should know about safety. I plan to do it outside with a respirator and safety goggles, but I just want to make sure there’s nothing that I’m missing.

IMO if this is not frequently repeated and you have good ventilation then you will be OK - even without a gas mask

Although chlorine gas is very toxic, (a war gas / chemical weapon)
at hobby-level concentrations and exposure levels (other than major accidents)
you will run away from harm long before there is real danger due to the eye-watering choking-ness of chlorine gas.
This is based on multiple personal exposures over recent years,
but I'm old and a smoker,
- if you want to be 'safe' then ignore this comment ;)

Make sure that the cartridges for your mask are suitable and the mask has an airtight seal to your face.

In general always have an appropriate 'antidote' available.
My 'favourite' for outdoor work is a garden hose pipe operated at the nozzle end for immediate use.

Chlorine gas is really good at corroding metals - Keck clips, water taps and sinks included :)

Assuming you will generate chlorine from an oxidizer and hydrochloric acid do not assume they all act the same. I have not had any troubles with chlorine gas but i have made sure to work with it on windy days but it is probably not necessary. It is a heavy gas though.
