Poisonous Plants

Poisonous plants are common on or near construction sites. Most people develop a skin rash and skin irritations lasting up to three weeks when they contact poison ivy or poison oak. The reaction is caused by urushiol (“oo-roo-shee-ohl”) oil found in the sap. The oil is in the stems, leaves and berries of these plants and can be transmitted by brushing against the plant, or from secondary contact with animals or clothing.

Poison ivy

Found throughout the United States, except in the Southwest, Alaska and Hawaii, poison ivy has three shiny green leaves, a red stem and typically grows in the form of a vine, often along riverbanks, roadsides and woodlands. Old vines are very hairy; in late summer and fall the vines will have green-to-white berries. Poison ivy is most dangerous in the spring and summer, when they have plenty of sap and a high content of urushiol. However, cases have been reported in people who used the twigs of the plant for firewood or the vines for Christmas wreaths. Even dead plants can cause a reaction, because the oil remains active for several years after the plant dies.

Poison oak

Poison oak grows as a low shrub in the eastern part of the U.S. (from New Jersey to Texas), and as 6-foot-tall clumps or vines up to 30 feet long along the Pacific coast. It has oak-like leaves, usually in clusters of three and clusters of yellow berries.

Treatment if you’re exposed:

  • First, cleanse the exposed skin with generous amounts of isopropyl (rubbing) alcohol. (Note: alcohol removes your skin’s natural protection along with the urushiol, so avoid any additional contact because skin washed with alcohol will allow the urushiol to penetrate twice as fast.)
  • Second, wash the affected area with water.
  • Third, take a regular shower with soap and warm water. Do not use soap before this point because soap tends to pick up some of the urushiol from the skin’s surface and move it around.
  • Clean clothes, shoes, tools and anything else that may have been in contact with the urushiol with alcohol and water, then wash with soap and water. Be sure to protect your hands during this process.
  • To help reduce the itchiness, apply lotions with an anti-inflammatory and cooling effects (talc, calamine). Oral antihistamines can also relieve itching.

Poison ivy blisters don’t contain urushiol, so any oozing fluid is not contagious and will not spread the rash further. A rash will only occur where urushiol has touched the skin. However, the rash may seem to spread if it appears over time instead of all at once, because the urushiol is absorbed at different rates in different parts of the body, is trapped under the fingernails, or because of repeated exposure to contaminated objects.

The American Academy of Dermatology recommends that people who have had severe reactions in the past to any of these plants, contact a dermatologist as soon as possible after a new exposure.

Trench collapses can occur without warning, regardless of the depth. The vast majority of trenching fatalities occur in trenches 5 to 15 feet deep. But trench cave-ins don’t have to happen. They are preventable with proper planning and execution of safety precautions.

Here are some practices that will help reduce the risk of on-the-job injuries or fatalities on excavation sites.

  1. Know where the underground utilities are located before digging.
  2. Keep excavated soil (spoils) and other materials at least two feet from trench edges.
  3. Keep heavy equipment away from trench edges.
  4. Identify any equipment or activities that could affect trench stability.
  5. Test for atmospheric hazards such as low oxygen, hazardous fumes, and toxic gases when workers are in trenches more than four feet deep.
  6. Inspect trenches at the start of each shift. This should be done by the competent person. The competent person should be authorized to order immediate corrective action, including restricting entry into the excavation, until any hazards or potential hazards have been eliminated.
  7. Ensure that employees working in trenches four feet deep or more have an adequate and safe means of exit, such as ladders, steps or ramps. These must be within 25 feet of all workers at all times and will need to be relocated as the job progresses.
  8. Inspect trenches following a rainstorm or other water intrusion.
  9. Inspect trenches after any occurrence that could have changed conditions in the trench.
  10. Do not work under suspended or raised loads or materials.
  11. Ensure that workers wear high-visibility or other suitable clothing when exposed to vehicular traffic.
  12. Develop a trench emergency action plan and train workers and supervisors on the proper actions to take in case of an emergency.

Remember: Unlike most accidents, the cave-in of an excavation can usually be predicted if closely watched. So stay alert. Don’t take anything for granted.

Heat Stress

Working in a hot environment, such as a construction site, puts stress on the body’s cooling system. When heat is combined with other work stresses – like hard physical labor, loss of fluids, or fatigue – it may lead to heat-related illness, disability or even death. There are three stages to heat-related illness: heat cramps, heat exhaustion and heat stroke.

Heat cramps are painful, brief muscle cramps that are brought on because the body has lost minerals through sweating. If cramping occurs, move to a cool area at once. Loosen clothing and drink cool water or an electrolyte replacement beverage. Seek medical aid if the cramps are severe, or don’t go away.

Heat exhaustion can occur after you’ve been exposed to high temperatures for several days and have become dehydrated. Symptoms include confusion, dizziness, headache, fatigue and sometimes nausea. Without proper intervention, heat exhaustion can progress to heat stroke. If you experience heat exhaustion, get out of the heat immediately and rest, preferably in an air-conditioned environment. If you can’t get inside, try to find the nearest cool and shady place. Slowly drink fluids. If possible, lie down with your feet and legs slightly elevated.

Heat stroke is the most serious form of heat illness and is a medical emergency. It often occurs after heat cramps or heat exhaustion are not properly cared for. But it can strike even if you have no previous signs of heat illness.

Heat stroke can kill, or cause damage to the brain and other internal organs. Symptoms are similar to heat exhaustion, but the skin is hot and dry and breathing is deep and fast. The victim may collapse. The body is no longer able to sweat, and the body temperature rises dangerously. If you suspect that someone is a victim of heat stroke – also known as sun stroke – call 911 immediately. Move the victim to a cool area and remove excess clothing while waiting on help to arrive. Fan and spray them with cool water. Offer sips of water if the victim is conscious.

There are things you can do to prevent heat-related illnesses.

  • Drink plenty of fluids. Consider beverages that replace electrolytes. Stay away from beverages with caffeine. Caffeine contributes to dehydration.
  • Slow down in hot weather. Your body’s temperature-regulating system faces a much greater workload when the temperature and humidity are high.
  • If possible, get accustomed to the heat gradually.
  • Dress for hot weather. Light colored clothing reflects heat.
  • Get out of the heat occasionally. Take breaks in a cool, shady location.
  • Eat light, cool meals.

Heavy Equipment Safety

Posted on by admin_ici

Only trained, highly skilled construction workers should operate heavy equipment such as excavators, loaders, graders, rollers and bulldozers. Ground-based workers should be trained in how to work safely around the equipment or stay clear. Unsafe practices by either the operator or those around the equipment can create very dangerous situations. Some of the reasons for injury to heavy equipment operators and ground-based workers on a construction site include:

  • Repairing and servicing equipment in dangerous positions,
  • Striking individuals or other vehicles with the equipment – particularly the blade,
  • Unexpected tipping of equipment,
  • Uncontrolled traffic within or through the work area,
  • Unexpected shocks or jars to the machine,
  • Sudden movement of a power unit while it is being attached to earth moving equipment,
  • Limbs of trees or overhead obstructions,
  • Leaving equipment running or in dangerous positions while unattended, and
  • Lifting mechanism failure on the equipment.

Here are a few common safety rules for operators and ground-based workers to consider:

  • Inspect and service your equipment regularly. This should be done in accordance with the manufacturer’s recommendations and by qualified personnel. A pre-shift walk around inspection by the operator is highly recommended.
  • Do not wear loose clothing that can get caught in moving parts of the equipment.
  • Keep deck plates or steps on equipment free from grease, oil, ice and mud. Corded soled shoes are recommended.
  • Check the area for ground-based workers before operating the equipment.
  • Ground-based workers should wear high visibility clothing so they can be seen by the operator. They should also wear their personal protective equipment.
  • Establish a danger zone for ground workers. Be aware of the swing radius on certain equipment and, if possible, cordon off the area with barriers or caution tape.
  • Use a spotter and establish a standardized set of hand signals to be used by the operator and spotter. Two-way radios can sometimes be valuable communication tools.
  • The spotter should maintain eye contact with the operator. This will ensure that they are not in the operator’s blind spot.
  • Make sure the back-up alarm on the equipment is in working order and use it when backing.
  • Employees other than the operator should not ride on equipment.
  • Before starting the motor, the operator should make sure that all operating controls are in the neutral position.
  • Heavy equipment should have a rollover protective structure that meets OSHA requirements.
  • Operator should wear a seat belt at all times.
  • If working on slopes, try to avoid moving across the face of the slope. Operating up and down the slope is best.
  • Keep a safe distance from open excavations.
  • Wear hearing protection when required.
  • Never jump onto or off the equipment. Operators should always use the three-point contact rule when climbing on or off equipment. This means having either both feet and one hand, or having one foot and both hands in contact with the ladder access at all times.
  • If possible, drive equipment entirely off the road at night. If any portion of the machine projects into the road, it should be adequately marked with red lights or flares at night. Use red flags in the daytime.

Injury accidents involving heavy equipment have a high probability of fatality. It is critical that you know and follow your company’s safety rules and procedures when operating or working around heavy equipment.

Work zone flaggers are the first line of defense for road construction workers and are there to help protect the public. It is a critical and dangerous job. Because they are the ones that deal with the speeding, distracted or sometimes angry driver, they must also know how to protect themselves while on the job.

What flaggers should do to protect themselves:

  • Most importantly, all flaggers should have the appropriate flagger training and have periodic refresher training.
  • Wear high-visibility clothing such as orange, yellow or green vests. Use retro-reflective vests at night.
  • Wear other protective equipment such as hard hats, long-sleeved shirts and pants, safety footwear and eyewear.
  • Dress appropriately for the weather.
  • Stay alert and out of harm’s way by following these guidelines:
    • Stand alone on the shoulder in clear view.
    • Never stand in the open traffic lane.
    • Plan an escape route for emergencies.
    • Stay alert and focused on your work.
    • Make sure your hand signals don’t conflict with the traffic signals.
    • Treat motorists with respect and courtesy. Don’t pick fights or respond in anger. If a driver is a problem, record the make, model and license number of the car, and report the incident to law enforcement.
    • If a driver violates your warnings and trespasses your flagging station, warn the other workers in the work zone. Establish a warning signal ahead of time for the work crew in case of an emergency.

Dangerous behaviors flaggers should avoid:

  • Standing where you can be crushed;
  • Standing in the shade, over the crest of a hill or around a sharp curve;
  • Leaving your position until properly relieved;
  • Standing near equipment;
  • Standing in a group;
  • Participating in unnecessary conversation;
  • Reading or daydreaming while on duty;
  • Using your cell phone;
  • Listening to music or using ear phones; or
  • Turning your back on traffic.

Remember, working in traffic areas always presents some risks. The job of a flagger is an essential component of worksite safety.

Tips for the Safety Supervisor

Posted on by admin_ici
Originally published 05/31/2017

In past Toolbox Talks, we have discussed the safety responsibilities of construction workers. This week, we’ll discuss ten tips for supervisors to use when supervising safety.

  1. Demonstrate a genuine concern for worker safety. Be sure your workers understand and accept personal responsibility for safety. Provide them with the proper tools to get the job done. Reinforce safety where required and lead by example.
  1. Know the rules of safety that apply to the work you supervise. Be aware of the precautions required on the job. Attend safety training to gain knowledge of safety hazards.
  1. Anticipate risks that may arise from changes in equipment or methods. Use available safety information and advice to help guard against new hazards. It may be appropriate to conduct a periodic hazard assessment of the tasks your workers perform to determine the safest method and what personal protective equipment is needed for each job.
  1. Encourage workers to help identify hazards on the job and recommend a solution. Also encourage workers to stop work on a job if they have unanswered safety questions. Let them know that providing input on safety is not only allowed, but strongly recommended.
  1. Instruct your employees to work safely, with persistence and patience. When you observe employees who are not observing the safety rules, correct the unsafe behavior immediately. Unsafe work practices that go uncorrected can have long-term effects on your safety program.
  1. Follow up on safety issues and suggestions. Keep your workers involved in your company safety program. All safety suggestions and questions deserve a response. When communication breaks down and supervisors do not respond to workers’ suggestions, workers can easily lose interest.
  1. Set a good example. Demonstrate safety in your own work habits and personal conduct so that you don’t appear hypocritical in the eyes of your workers.
  1. Analyze all accidents and near-misses. When minor injuries go unheeded, crippling accidents may strike later. Minor accidents and near-misses provide an opportunity for safety improvements that could result in avoiding a serious accident or fatality.
  1. Recognize your role in the company’s overall safety program. It is vital to know that the company’s safety director does not own the safety program and that your involvement and input is welcomed and encouraged.
  1. Embrace your supervisory role and carry it out. Remember that managing safety on the job is as important as managing the project itself. Safety on the job is an investment that always pays dividends. Every effort that we make to prevent accidents on the job leads to a more productive work atmosphere and can contribute to improved employee morale.
