Maybe someone can help me with an interesting dilemma. When dealing with toxic chemicals the notation is always to wear a particular type of protective suit or eye protection when there is a splash hazard.

The problem is how do you define a splash hazard? While it may seem obvious to most that a splash is a splash, you get wet, but when dealing with very toxic or corrosive chemicals a splash is not necessarily what you would expect, in that 1ml of liquid may be sufficient to penetrate a suit.

Any ideas?

Thanks

Kevin

Kevin,

You need to refer to EN test standards to define what your PPE is tested to.

The problem is that this will tell you a splash is a splash.

The question you need to ask is whether the material of the suit will protect against your product, for how long, and is this adequate for the task.

Thanks John,

exactly.

The need for this is the basis for moving from one particular protective suit to the next higher protective level. If I say it is "where there is a splash hazard", our definition and comprehension of a splash maybe/will be different, so as a matter of clarity trying to determine that definition of cross over is where we are at the moment.

Suffice to say we are dealing with very toxic chemicals, with vapour properties being one thing, liquid properties much worse.

Simple enough to say it is not simple.

Cheers

Kevin,

what chemicals are you using and what type of work are you undertaking (maint, off-loading etc.)

I've always used "An uncontrolled release of liquid" to define a splash. This then covers liquid splashes of all sizes.

Hope that helps

Hi John,

lets just say with the chemicals they don't get much more toxic.

cheers

Kevin,

I can't really offer any advice other than contact a protective suit supplier.

Unless you know the strength and the product its difficult to determine your answer.

Splash resistant suits are just that, designed to allow you to escape in case of a release. They are not, on the whole, aimed at allowing users to get in and tackling torrents of liquid where a gas tight suit would be more appropriate.

I'm used to dealing with Hydrofluoric acid at various strengths but would recommend different suits based on exposure time, strength, mechanical properties, cost etc. The size of splash/spray is often difficult to determine so its a belt and braces approach,

John
