Mitchell Pountney, aged 23 and from Stourbridge, died on September 2 at Cutting Edge Skirting on Station Road, Rowley Regis.
An inquest at Black Country Coroner's Court in Oldbury was told today how questions remain over Mr Pountney's death – with no direct witnesses to the incident and no CCTV footage.
Jenny Skeldon, from the Health and Safety Executive (HSE), said: "A specialist attended the site on the day it happened and is in the process of completing a report in November or December.
"My investigation is ongoing. I have been to the site and taken statements, but it is ongoing and I have further lines of enquiry to follow up.
"There's no direct witnesses and no CCTV of the incident itself."
Solicitor Bob Davies, from law firm BLM, acting on behalf of Cutting Edge Skirting, said: "I want to say I've been asked by the company to express our sincere condolences – from the directors and the staff – to the family for the sad and tragic accident.
"Mitch was very well liked by the workers there and it's been a very tragic incident.
"The company will do all it can to assist the HSE."
A further pre-inquest hearing will take place on December 10, Coroner Zafar Siddique said.
