Wood Fabricating Assembler Died After Being Crushed by a Wooden Flange in California
FACE REPORT: 95CA00501
DATE: DECEMBER 6, 1995
A 42-year-old male, Hispanic wood fabricating assembler (the victim) died when a wooden flange he was attempting to roll to an assembly rack (jig) fell over and crushed him. The flange was 92" in diameter and weighed approximately 350 pounds. It was being rolled manually 25 feet to the assembly area where it was to become part of a reel or spool used to store wire. The victim's employer stated that rolling flanges was the typical method used to move them from the entrance way to the jig. The employer also stated that the victim was familiar with the hazards involved in rolling the flange. The concrete surface on which the flange was being rolled was flat, but was wet from recent rains. Though there were no witnesses to the incident, a co-worker in the general vicinity heard a loud noise when the flange fell to the ground. He ran to see what had happened and discovered the victim underneath the flange. The co-worker lifted the flange from the victim's head and summoned emergency services to the scene. Fire department paramedics arrived in approximately 5 minutes and transported the victim to a community hospital where he was later pronounced dead. The CA/FACE investigator concluded that in order to prevent similar future occurrences, employers should:
- evaluate their manual materials handling procedures assuring that safe methods are used.
- conduct job safety analyses on all tasks in order to identify potential hazards before initiating and continuing work at a job site. Once hazards have been identified, appropriate corrective actions should be taken.
- implement and maintain a written Injury & Illness Prevention Program (IIPP) which addresses the hazards associated with, and the specific safety training necessary for materials handling.
On March 22, 1995, a 42-year-old manufacturing assembler (the victim) died after being crushed by a wooden flange he was attempting to roll to an assembly area. The CA/FACE investigator was informed of this incident by a California Occupational Safety & Health Administration (Cal/OSHA) district office. The CA/FACE investigator conducted a site investigation on April 4, 1995. The site investigation included interviewing the company manager, the victim's co-worker, and taking photographs of the incident site. A copy of the CAL/OSHA Report, the Sheriff-Coroner's Autopsy Report, and the Police Report were all obtained by the CA/FACE investigator.
The employer in this incident was a manufacturer of wooden reels or flanges. Once assembled, different types of wire. The company employed 40 workers at several different locations, with three workers employed at the incident site. The company had been in business for 70 years and had worked at this particular site for 18 months. The victim had worked for the company for seven months spending his entire time at the incident location. There were no specific safety procedures for the task the victim was performing, a task he had performed on numerous occasions. The on-site supervisor was the designated safety officer. There were no written safety policies, but the supervisor stated that monthly safety meetings were held.
On the day of the incident, at 1:30 p.m., the victim was retrieving and transporting large wooden flanges from the storage yard to the assembly area. This task involved two activities. In the first step, employees used a forklift to transport flanges from the storage area to the door of the assembly area, a distance of approximately 100 yards. In the second step, employees manually rolled the flanges from the forklift to the assembly area, a distance of about 25 feet. The flanges were not moved the entire distance to the jig with the forklift because workers needed to keep the assembly area clear for other activities. There were two workers at the site, the victim and a temporary worker. The temporary worker was in a different part of the building while the victim was moving the flanges. There were several different size flanges in the storage area. The victim was transporting the largest flanges which weighed approximately 350 pounds each and were 92 inches in diameter (see Exhibit 1).
The temporary worker stated that he heard a noise when the flange hit the ground and he ran to see what had happened. He found the victim underneath the flange just inside the door to the assembly area. He removed the flange from the victim's head and summoned emergency services to the scene. Fire department paramedics arrived in approximately five minutes and transported the victim to a community hospital. He was pronounced dead by a physician at the hospital at 2:17 p.m.
The victim's supervisor explained that the company safety rule stated that employees should leave enough room to run out of the way if the flange should fall while being transported to the assembly area. According to the victim's supervisor and co-workers, flanges would fall during this phase of the operation two to three times per week. Co-workers stated that when rolling large flanges into the assembly area two workers often worked together, although this was not an official operating procedure. On the day of the incident, the concrete surface on which the flanges were being rolled was level but was wet from recent rains. It is not known if the environmental conditions contributed to this fatal event.
CAUSE OF DEATH
The Sheriff-Coroner's Autopsy Report stated the cause of death as craniocerebral trauma.
Recommendation #1: Employers should evaluate their materials handling procedures and assure that safe methods are used.
Discussion: In this incident, a forklift was used to transport flanges from the storage area to the entrance of the assembly area. The flange was then manually transported from the entrance area to the jig. This change in method of transport for the last 25 feet of the operation placed workers at high risk for injury. This fatality may have been prevented by use of an alternative method of retrieval in the second phase of transport such as, the continuous and sole use of a forklift, or use of a dolly or cart system. Frequent movement of the same types of material over the same routes suggests the use of mechanization, particularly where there is manual handling of heavy or unstable objects. Under Title 8 of the California Code of Regulations (CCRs) section 3328 (e), machinery and equipment components shall be designed, secured, or covered to minimize hazards caused by breakage, release of mechanical energy (e.g. broken springs), or loosening and falling.
Recommendation #2: Employers should conduct job safety analyses on all tasks in order to identify potential hazards before initiating and continuing work at a job site and on an ongoing basis. Once hazards have been identified, appropriate corrective actions should be taken.
Discussion: In this situation, it was known that the large, heavy flanges fell repeatedly, but no one at the worksite had identified this as a hazard requiring control measures. Employers should be aware of the hazardous conditions at jobsites and should take an active role to eliminate them. Regular safety inspections, conducted by the employer or supervisor familiar with the work processes, may have assisted both the employer and the employees in raising their awareness regarding the hazards to which they were exposed. Even though safety inspections do not guarantee the prevention of occupational injury, they are key to identifying unsafe conditions and activities that need to be rectified. Further, they demonstrate the employer's commitment to the enforcement of the safety program and to the prevention of occupational injury.
Recommendation #3: Employers should implement and maintain a written Injury & Illness Prevention Program (IIPP) which addresses the hazards associated with materials handling.
Discussion: The employer in this situation conducted intermittent safety meetings, but a comprehensive safety training program did not exist. The process of planning and implementing a site-specific safety program may have assisted the employer in identifying previously unidentified hazardous conditions. Under Title 8 of the CCRs section 3203 (a)(7)(B), employers must provide training and instruction to all new employees given new job assignments for which training has not previously been received. With the implementation of a safer materials handling process, it would be important to implement a thorough training program regarding the new procedures.
