thanks in advance

What you need to do depends very much on the concentration of the acid, the temperature, the quantity, what you are doing with it and where.
Can you give us some more details?

Hi Leanne,
A good place to start is the MSDS is you have one. It should tell you correct PPE to wear, and what to do in emergency situations. This will help with your risk assessment.
Mick.

Posted By Kate Graham Try www.coshh-essentials.org.uk which will take you through the process of a COSHH assessment. You can't rely on the msds to tell you what PPE to wear - the person who wrote it doesn't know what you are doing with the sulphuric acid so cannot give specific advice. They have to include this guidance but they usually cover themselves to the point that it's worthless. For example if you go by the msds for sodium chloride and acetic acid you will find you need overalls, safety boots and googles to put salt and vinegar on your fish and chips. Kate

I agree. The average MSDS is virtually worthless as it is mainly a bum-covering exercise. It does however alert you to the more significant hazards which should be taken into account.
More important are the conditions of use : quantity, control measures, temperatures, agitation, ventilation, length of use etc.
Does anyone remember the MSDS for H2O ? "Viciously corrosive for a range of metals, should not be imbibed in large quantities unless suitably diluted by other chemical products (scotch, gin, vodka ...)
Waste products can be recycled as-is. (see Watney's Red Barrel)"

What about the chemists poem?
Johnny was a chemist's son, but Johnny is no more.
What Johnny thought was H20, was H2SO4
