avoid warehouse workplace injuries

Injuries at work have become something we all hear about, either due to someone suing their employer, the employer complaining about the number of working days lost to being signed off, or simply because the story was funny, like the incident report on the hapless labourer that met the bucket on the way down… Don’t remember? Let me remind you:
"Dear Sir I am writing to further elaborate on the incident and complete the accident report form. "Poor planning" was the cause and I hope find this explained further.
I am a bricklayer by trade. On the day of the accident, I was working alone on the roof of a new six story building. On completion, I found some bricks left over which, (when weighed later) were found to be slightly in excess of 600 lbs. Instead of carrying the bricks down by hand, I decided to lower them in a barrel by using a pulley. Securing the rope at ground level, I went up to the roof, swung the barrel out and loaded the bricks into it.
At the bottom, I untied the rope and held it tightly to ensure a slow descent of the bricks. I refer to Block 10 on the report that I am 140lbs. Due to my surprise at being jerked off the ground so dramatically, I forgot to let go of the rope. Upon realisation of what I had done, I was still proceeding up the side of the building very quickly. At about the 3rd floor, I came face to face with barrel which was hurtling downwards at a truly impressive speed.
This is the explanation I offer for my fractured skull, minor abrasions and broken collar bone.
