Dehydration

Peak construction season usually means working on hot summer days with soaring temperatures. There are several problems that can occur while working on a construction site in such conditions, however the most common is dehydration.

Dehydration occurs when your body does not have enough fluid. It can be caused by losing too much fluid, not drinking enough fluids, or both. In hot weather, your body expels a lot of water through perspiration as it tries to keep from overheating. The hotter the weather, the more you perspire and the more fluids you need to replace.

A widely held misconception is that everyone needs 64 ounces (eight cups) of fluid each day. While these quantities are appropriate for most people, they don’t take into account a person’s body size or activity level. Though no single formula fits everyone, some nutritionists contend that a more accurate way to determine your fluid requirement is to divide your body weight in half. This is how many ounces of fluid you need daily to meet your basic needs. So a 150-pound person would need to drink at least 75 ounces (just over nine cups) of fluid daily, while a 200-pound individual requires at least 100 ounces (about 12.5 cups).

Levels of dehydration can range from mild to severe based upon how much of the body’s fluid is lost and not replenished. Dehydration can escalate and become a life-threatening illness. Therefore, it is very important to recognize the signs and symptoms of dehydration. These signs and symptoms generally include:

  • Dry or sticky mouth
  • Low or no urine output (concentrated urine appears dark yellow)
  • Light-headedness or dizziness
  • Dry skin
  • Fatigue
  • Confusion
  • Nausea
  • Increased heart rate and breathing

To treat dehydration, re-hydrate the body by drinking plenty of fluids. Stay away from caffeinated drinks. Also, recognize the fact that if you are dehydrated, you have lost sugar, salts and minerals, as well as water. Re-hydration solutions such as sports drinks can be very helpful in this instance.

As with all on-the-job illnesses, prevention is key. During hot and humid weather, don’t neglect your fluid consumption. Don’t wait until you feel thirsty to drink fluids. Once you start to feel thirsty, dehydration could have already begun. Light-weight, light-colored, breathable clothing can also make a difference. Every effort you make to stay cool on hot summer days will go a long way toward staying safe on a construction site.

Silent Warnings

Signs are used to communicate important messages. Signs on a construction jobsite are essential for everyone’s safety.

We see these signs every day. Signs that remind workers of the dangers of working in and around confined spaces or electrical hazards. Signs that alert motorists to the existence of a work zone, warning them to watch out for workers. Signs on containers that provide a list of contents or special instructions. For the most part, we recognize the messages conveyed on these signs and react accordingly.

But what are silent warnings that point to safety hazards with the potential to cause harm? Examples include:

  • a hole in the floor
  • a leaning pile of material
  • a flagger station just over the crest of a hill
  • a worker sitting on a barrier in a construction zone
  • protruding nails
  • an unprotected trench
  • an uncovered rebar protruding upward
  • falling material
  • defective tools

Learn to recognize a silent warning just as readily as you would a sign with words, then take prompt action to prevent accidents.

Don’t assume it’s not your responsibility to deal with a problem just because you didn’t create it, or it’s not in your normal work area. Instead, deal with the issue immediately. Prompt corrective action could mean the difference between a safe working environment, you or a co-worker suffering an unnecessary injury – or worse. Don’t ignore a hazard. Don’t assume someone else will deal with it. If it is something you cannot handle without putting yourself in danger or violating company policy, then immediately report the hazard to a supervisor.

Be alert. Make every effort to observe these less obvious warning signs, because they point to potential accidents waiting to happen. When you do recognize potential safety hazards, take action. Promptly and responsibly take steps to ensure they are corrected.

“A place for everything and everything in its place” applies even in construction. Safe housekeeping requires some extra effort, but the benefits are a safer work environment and less chance of an accident or injury.

OSHA Standards for Stacking and Storing Materials (taken from Standard 1926.250):

  • All materials stored in tiers should be stacked, racked, blocked, interlocked, or otherwise secured to prevent sliding, falling or collapse.
  • Maximum safe load limits of floors within buildings and structures, in pounds per square foot, should be conspicuously posted in all storage areas, except for floor or slab on grade.
  • Aisles and passageways must be kept clear and in good repair to provide for the free and safe movement of material handling equipment or employees.
  • When a difference in road or working levels exist, such as ramps, blocking or grading should be used to ensure the safe movement of vehicles between the two levels.
  • Remove all nails from used lumber before stacking.
  • Stack bags and bundles in interlocking rows to keep them secure.
  • Stack bagged material by stepping back the layers and cross-keying the bags at least every ten layers. (To remove bags from the stack, start from the top row first.)
  • Stack and block poles as well as structural steel, bar stock, and other cylindrical materials to prevent spreading or tilting unless they are in racks.
  • Materials stored inside buildings under construction shall not be placed within six feet of any hoistway or inside floor openings, or within 10 feet of an exterior wall that does not extend above the top of the stored material.
  • Non-compatible materials should be segregated when stored.
  • Do not store materials on scaffolds or runways in excess of supplies needed for immediate operations.
  • Storage areas should be kept free from accumulation of materials that constitute hazards from tripping, fire, explosion or pest harborage. Vegetation control should be exercised when necessary.

Remember, bad housekeeping can lead to accidents. It is important that OSHA standards for stacking and storage be followed at all times. Make this a habit and keep the jobsite safe for everyone.

Load Binder Safety

Load binders play an important role in construction, but we don’t give them much thought until we need one. There are several types of load binders. Generally, they have hooks attached to chains on either side of a sturdy metal lever and are used to tie down and secure equipment and materials for transport and delivery. Load binders can be very dangerous. Accidents can occur quickly and often result in serious injury.

Here are some safety tips to follow when using load binders:

  1. Inspect a load binder prior to use. Look for excessive wear, bending, cracks or damage. If in doubt, don’t use it.
  2. Keep your head and body out of the path of the load binder’s handle because it can suddenly spring back and causing serious injury.
  3. Wear a hard hat, gloves and eye protection whenever you are tightening or loosening a load binder.
  4. Never tighten or loosen a load binder while standing on the load being secured or loosened.
  5. When tightening or loosening a load binder, make sure that you have firm footing and are not standing on ice, snow, loose rocks, oily surfaces, etc.
  6. After you have secured the load with a load binder, make sure the lever handle is in the locked position and tie the handle in place with wire or chain when done.
  7. Use an open hand (do not grip the binder handle) when releasing a load binder. Keep your body out of the way and push the lever open.
  8. Be especially careful when you are releasing the tension, as the handle can snap back quickly. As equipment and material are transported, they can shift causing an increase in tension on the load binder. This extra tension will be suddenly released as you loosen the load binder, which will cause the lever handle to jump.
  9. Do not use a pipe to help you apply extra leverage to a load binder handle, unless the manufacturer has approved or supplied that pipe as a handle extender. These pipes can fail suddenly, or slide off suddenly, causing injury to yourself or nearby co-workers.

Attitude & Behavior – Major Causes of Accidents

There are potential hazards on any construction site. In many cases, whether or not we get hurt depends on how we approach these dangers and deal with them. To a certain extent, safety is instinctive. For example, we seem to be born with a fear of falling. In other instances, safety is not instinctive. It has to be learned and practiced. Why do some people ignore the dangers they’ve been warned about, while others take heed? The differences are EXPERIENCE and ATTITUDE.

In almost any operation, accidents caused by unsafe environmental conditions or mechanical failures tend to be easiest to control, at least potentially. However, human behavior – identified as a leading cause of accidents – is harder to manage. Everyone should be aware of the human factors that can contribute to an accident.

Ignorance. This condition may stem from lack of experience, the inability to recognize a hazard or lack of job training. Don’t guess or take chances. Ask questions, and be sure you understand your job and its dangers.

Daring. This type of worker believes he can beat the odds. Maybe he can, for a while. It’s like playing Russian roulette. Will you find the bullet on the first trigger pull or on the sixth? Some jobs are so full of danger they can be likened to having more than one bullet in the cylinder. In other words, in some conditions your odds of being hurt are greater. There are enough dangers in construction without taking extra chances.

Poor Work Habits. These sometimes come with familiarity, or they may begin on the first day of the job. Don’t become complacent just because you’ve been taking shortcuts and have been getting away with it. Set an example for the younger, less experienced worker.

Haste. We are all familiar with the adage, “Haste makes waste.” It’s true. An accident is always costlier than the value of the time saved. Not only can it result in medical bills, but there may also be damage to equipment, loss of production and other “hidden costs.” Work at a steady, efficient pace and work smart.

Physical Failure or Fatigue. Exhaustion can limit your concentration, coordination, eyesight and judgment. Pace yourself and get enough sleep when you have work to do. Don’t abuse drugs or alcohol. Tests have shown the effects of these substances can last for days, even if you seem to feel fine.

Work smart and work safe. If you maintain a positive attitude toward safety, you’ll live longer and be better off in many ways.

Jackhammers and Chipping Concrete

Posted on by admin_ici

It is sometimes necessary in bridge and highway repair, to remove small amounts of concrete. Compact pneumatic chipping hammers (jackhammers) are often used to do the job. These compact battering rams pack a lot of punch, and they can be dangerous if not used properly. Here are some common-sense tips provided by tool manufacturers.

Dress Appropriately to Protect Yourself

  • Everyone in the area should always wear impact-resistant eye protection.
  • Depending on the situation, wear a facemask or respirator.
  • Wear a hardhat, especially if there is a risk from falling objects.
  • Wear adequate clothing that fits properly.
  • Wear proper hearing protection.
  • Wear gloves to protect your hands and steel-tipped boots to protect your feet.
  • Set up screens to prevent nearby workers from being struck by flying fragments.

Inspect the Jackhammer and Tools Before Use

  • Carefully inspect the jackhammer for damage and make sure all controls and safety interlocks work properly.
  • Inspect air hose connections at the air compressor and the jackhammer for cracks, worn threads and loose couplings.
  • Inspect the safety clip or tool retainer for proper operation. This prevents the chisel/tool from being unintentionally shot from the barrel.
  • Check the chisel/tool for tightness of fit and excessive wear. Repair or replace when required, following the manufacturer’s recommendations.

Beware of Air Under Pressure

  • Never engage in horseplay with compressed air – it’s dangerous!
  • Always disconnect the tool when it is not in use or when you are changing accessories.
  • Never exceed the tool’s designated operating pressure.

Proceed With Caution

  • Always keep both hands on the tool.
  • Watch for excess lengths of the air hose, which can cause you to trip.
  • Never operate the tool without the chisel against the work surface.
  • Discontinue use if numbness, tingling, pain, or flushing of the skin occurs.
  • Prevent back injuries by using your leg muscles to lift the jackhammer into position.
  • Allow the tool to do the work by using a grip light enough to maintain control.
  • Always follow any special manufacturer instructions.

Work smart and work safe when using jackhammers or any other equipment on the jobsite.
