The use and non-use of seat belts in the operation of forward tipping dumpers

In the event of a forward tipping dumper (FTD) overturning, the operator will be protected from death and serious injury by wearing their seat belt. The seat belt works in combination with the roll over protection system (ROPS) to keep the operator in their seat, preventing them being crushed by the machine.
Unfortunately, a proportion of operators choose to operate FTDs without wearing a seat belt and thus increasing their risk of death or serious injury should the machine overturn. Using semi-structured interviews to gauge the opinions of trainers, original equipment manufacturers, seat and seat belt manufacturers and FTD operators, this research aimed to better understand the reasons why FTD operators choose not to wear their seat belt when operating their machines.
The research also explored potential solutions that would encourage operators to wear their seat belt more, including possible design control measures such as immobilisation technology, alternative designs of seats and seat belts, and of the overall FTD machine.

Adherence to Precautionary Guidelines for Compounding Antineoplastic Drugs

A Survey of Nurses and Pharmacy Practitioners
Precautionary guidelines detailing standards of practice and equipment to eliminate or minimize exposure to antineoplastic drugs during handling activities have been available for nearly three decades. To evaluate practices for compounding antineoplastic drugs, the NIOSH Health and Safety Practices Survey of Healthcare Workers was conducted among members of professional practice organizations representing primarily oncology nurses, pharmacists, and pharmacy technicians. This national survey is the first in over 20 years to examine selfreported use of engineering, administrative, and work practice controls and PPE by pharmacy practitioners for minimizing exposure to antineoplastic drugs. The survey was completed by 241 nurses and 183 pharmacy practitioners who compounded antineoplastic drugs in the seven days prior to the survey. They reported: not always wearing two pairs of chemotherapy gloves (85%, 47%, respectively) or even a single pair (8%, 10%); not always using closed system drug-transfer devices (75%, 53%); not always wearing recommended gown (38%, 20%); I.V. lines sometimes/always primed with antineoplastic drug (19%, 30%); and not always using either a biological safety cabinet or isolator (9%, 15%). They also reported lack of: hazard awareness training (9%, 13%); safe handling procédures (20%, 11%); and medical surveillance programs (61%, 45%). Both employers and healthcare workers share responsibility
for adhering to precautionary guidelines and other best practices. Employers can ensure that: workers are trained regularly; facility safe-handling procedures reflecting national guidelines are in place and support for their implementation is understood; engineering controls and PPE are available and workers know how to use them; and medical surveillance, exposure monitoring, and other administrative controls are in place. Workers can seek out training, understand and follow facility procedures, be role models for junior staff, ask questions, and report any safety concerns.

One Size Does Not Fit All

When your safety and your life depends on it, you need your equipment to fit properly. This is especially true in the workplace. Improper fit may prevent workers from performing their job duties safely and effectively. If your respirator does not seal properly to your face, if your gloves are too big, if your seatbelt cannot buckle with your safety gear on . . . you get the picture.
Anthropometry is the science of defining human body dimensions and physical characteristics. The National Institute for Occupational Safety and Health (NIOSH) conducts anthropometric research to prevent work-related injuries and deaths by studying how work spaces and equipment fit today's diverse worker population. This includes the fit of machines, vehicles, and personal protective equipment (PPE). Much of the available data were collected in the 1950s and 1970s from military personnel and the general population from that era. These decades-old data do not represent, on average and collectively, the sizes and body types of today's workers, who are much more diverse in age, gender, and ethnicity. NIOSH research has shown workers have unique shapes and sizes for specific occupations.

Investigation into exposure when the visor of air fed RPE is raised during spraying

Air-fed visors (AFV) are commonly used within the Motor Vehicle Repair (MVR) trade for protection against exposure to isocyanate paints. However, a common practice amongst paint sprayers is to flip up the visor of their AFV immediately after spraying to check the quality of the paint finish. This may be only for a few seconds but if repeated numerous times during a work shift, this could potentially result in a significant increase in exposure. The aim of this project was to determine the reduction in protection and thus potential increase in exposure when the visor is lifted and to explore potential engineering solutions (by modifying the AFV design) to prevent exposure during any visor lift.
The results clearly demonstrate that lifting the visor whilst still within a contaminated atmosphere had a significant detrimental effect on the protection afforded by the AFV. Mean protection factors were measured at 1.7 in the lifted position and at 2.7 over the whole of the exposure period (from start of the lift to recovery of protection after refitting). This latter figure equates to a 15 fold increase in exposure when related to the assigned protection factor of40 for AFV when used correctly.
