Hi Kelly
Always pleased to help.
Please be careful of the maggots & flies, careful of the hepatitis B & C, HIV, aids, Radiation disease (if the deceased was having radiotherapy for any cancers), e.coli, salmonella, parasites carrying tapeworm, fleas or ringworm, fungi, bacteria, or flesh eating maggots.
You need to know before you enter what diseases he had, what medication he was taking, any treatments he was undergoing, whether the pet was eating him before he died, if the pet was taking anything or had any health issues, any needles in the area.
By law you need an exposure control plan, you have to adhere to stringent H&S requirements, have your housekeeping & welfare facilities procedures in order, by law you need to give your risk assessment and method statements about how you are going to do the work and what procedures are in place to protect both yourself and your staff, have they and you had you Hep B shots and the paperwork to back this up (these need to be kept for 30 years) that you PL ins covers you for blood bourne pathogens, what decontamination procedures you have in place.
By law you have to dispose of all and any sharps (needles, glass sharp bits of bone) in a proper sharps container, which by law has to be labelled with the proper bio hazard signs, who is transporting it with consignment numbers (kept for 30 years) specify in your risk assessment what PPE is to be used.
Please also make sure you are in compliance with the 1974 H&S at work act, The management of H&S at work regs 1999.
If she was lain on the carpet for 'several weeks' then she would of putrefied and the sub structure may have to come up as well (floorboards & joists) also you will need some serious odour control.
Get it right it should a nice earner, get it wrong, go to jail, do not pass go, do not collect.
Best of luck
Regards
Martin
