Explain three precautions that can be taken to alleviate the hazards associated with prolonged standing

Question

What will be an ideal response?

Answer 1

Prolonged standing or walking is common in construction. It can cause lower back pain, sore feet, swelling in the legs, general muscular fatigue, and other health problems. The following precautions can minimize standing hazards:
• Anti-Fatigue Mats. Anti-Fatigue mats provide cushioning between the feet and hard working surfaces such as concrete floors (see Figure 7-28). This cushioning effect can reduce muscle fatigue and lower back pain. However, too much cushioning can be just as bad as too little. Consequently, it is important to test mats on a trial basis before buying a large quantity. Mats that become slippery when wet should be avoided. In areas where chemicals are used, be sure to select mats that will hold up to chemicals.
• Shoe Inserts. When anti-fatigue mats are not feasible because employees must move from area to area and, correspondingly, from surface to surface, shoe inserts can help. Such inserts are worn inside the shoe and provide the same type of cushioning the mats provide. Shoe inserts can help reduce lower back, foot, and leg pain. It is important to ensure proper fit. If inserts make an employee's shoes too tight, they will do more harm than good. In such cases, employees may need to wear a slightly larger shoe size.
• Foot Rails. Foot rails added to machines such as saws can help relieve the hazards of prolonged standing. Foot rails allow employees to elevate one foot at a time four or five inches. The elevated foot rounds out the lower back, thereby relieving some of the pressure on the spinal column. Placement of a rail is important. It should not be placed in a position that inhibits movement or becomes a tripping hazard.
