Incident & Accident Report FormUse this form to report any personal injuries, near misses and any dangerous occurrences which take place on construction site premises.

DETAILS OF THE ACCIDENT / INCIDENT

Date 16th July, 2013 Time 15:30hrs

Describe the injury or incident:

What happened? How did it happen?

In July 2013, an adult male construction labourer (the victim) sustained fatal injuries after falling off a

collapsed steel beam connection at a steel building construction site. The steel beam connector was

26' 5½" long, 8' 3" wide and 8" thick, and weighed approximately six tons. The connector was

positioned on the building's steel structural frame composed of vertical steel columns and horizontal

steel beams. The beam connector was not secured to the steel framework at the time of the incident.

At approximately 9:20 a.m., the victim and a co-worker were on the structural frame using pry bars to

adjust the beam connectors into their final positions before they were to be permanently secured to

the steel framework. The southern section of the connectors rested on the horizontal steel beams and

its northern section was suspended (cantilevered) without the support of the steel beams. After the

two workers finished adjusting the beam connector, they both walked northward on the beam near its

east end. The connector suddenly tilted downward at its north side, rotated to a near vertical

position, and became wedged in between the steel supports. The co-worker secured himself with his

elbows onto the connector in front of him and climbed up. The victim fell to the floor below. The failed

steel beam connector then fell, struck the victim, and crashed through the concrete slab floor below.

 The co-worker immediately ran down to the victim and removed him from the collapsed zone. One of the workers called 911. Both police and an emergency service unit responded within minutes. The

victim was transported to a hospital where he died an hour later. The post incident investigation

found that a number of steel columns including the ones in the collapsed zone were erected out of 

plumb. The out-of-plumb columns led to increase spacing between the columns resulting in reduced

beam support for the connector located in-between these columns. The integrity of the initially failed

slab was further compromised by its notched shape and cantilevered section.

ACTION

  q What action has been taken to prevent a reoccurrence?  

It is my candid suggestion that, the following measures to help prevent similar incidents from occurring in the future, employers

should: comply with the structural dimensions and tolerances specified by the erection design and check vertical and horizontal

alignment of the steel structural frame before erecting any beam connectors; ensure that workers use personal fall protection

arrest systems when working on the steel beam connectors that are not permanently secured to the steel framework;

Provide employees with training on the prevention of fall hazards associated with working on the unsecured beam connectors;

and secure the beams to the steel structural frame by the method specified in the erection plan as soon as the beams are erected.
