Icepak, whose coolstore exploded last month killing one fireman and injuring seven others, had a large amount of flammable gas on site without the required safety certification.

Director Wayne Grattan told the Weekend Herald the company had about 200kg of propane LPG, which it used as a refrigerant, at its coolstores in Tamahere near Hamilton.

This is double the amount of flammable gas permitted without a location test certificate certifying that the plant met gas safety guidelines.

Certificates have to be lodged with the Environment Risk Management Authority (Erma) which oversees the Hazardous Substances and New Organisms (HSNO) Act 1996.

Erma confirmed to the Weekend Herald it has no record of a test certificate having been granted for Icepak's Tamahere plant.

Erma's hazardous substances general manager, Andrea Eng, said either a test certificate had not been granted or lodged.

Mr Grattan said the company had believed it complied with all regulations, even though it had more than 100kg of LPG - the amount that triggers the need for a location test certificate.

The company had not told the Waikato District Council that it was using propane as a refrigerant.

The opinion that the company complied with safety regulations came from "an electrical inspector who had tested our site for compliance with the NZ Standards, HSNO compliance," Mr Grattan said.

"It's not to say we haven't been tripped up here or done something wrong, but we certainly had had our plant inspected, we understood it complied with the regulations and we believed that we didn't need to notify the council of any change of refrigerant.

"Now that's not to say we shouldn't have done that but we believed we had complied with the rules."

Erma said electrical safety was covered by electricity regulations, not by the test certification rules set out in HSNO legislation. That involves an authorised test certifier making the site inspections.

Told in a subsequent interview that Erma had no record of a location test certificate for Icepak's Tamahere coolstores, Mr Grattan

told the Weekend Herald he did not believe the plant had such a certificate or that the person who examined the Tamahere plant was a test certifier.
