GETTING THE JUMP ON HEAT STREES-RELATED INCIDENTS

Remedial Construction Services, L.P. (RECON)As the temperatures start to rise in the Spring and Summer, keep a close eye out for heat stress-related signs and symptoms. I have witnessed, or been involved in, two heat stress-related incidents in the last two years. Neither turned out to be serious, but they could have been if we were not observing the individuals at the time. Both involved new workers to our sites so we were unfamiliar with these individuals, their habits, their acclamation to the summer heat, and their conditioning for physical labor. As with most of our safety incidents, new workers at a site (whether subcontractors or new hires) are the folks that are most vulnerable to being involved in a safety incident, and we want to observe them very closely for a few days. Use the buddy system, and make note of any unusual behavior or actions that may tell you that an individual is struggling. In both cases of heat stress, there were clear signs that the worker was not feeling well and needed a break from the heat even though they did not ask for one. I have seen the tendency to ignore or even antagonize individuals who may be struggling and out of shape physically. But, this is a mistake. Give workers the benefit of the doubt and allow them to cool down and get rehydrated, even if it seems unfair to other workers who are better conditioned and more productive. Everybody is different and works at different paces.


Heat Stress (Exhaustion) Symptoms:


•    Headache, dizziness, fainting
•    Weakness, wet skin
•    Irritability or confusion
•    Thirst, nausea, or vomiting
•    Pale or flushed complexion
•    Muscle cramps
•    Slightly elevated body temperature
•    Fast and shallow breathing

The Evolution of Construction Safety

Remedial Construction Services, L.P.Those of us that have been around the construction business for the past 20 or more years have experienced a huge increase in the participation from all levels of employees concerning safety.
In the early days when a HASP was written for a project, it was looked at as just another box that could be checked to start the work. HASPs were so voluminous nobody from the field level ever read them or in many cases could even understand them. Many Superintendents and Managers viewed safety as just a drain on the budget, something that reduced production and a lame excuse for some employees to be slow on the job. Near misses, minor injuries and incidents were ignored or hushed to avoid negative criticism from upper management. Whew! Glad those days are behind us.
Nowadays our HASPs and safe working procedures are viewed at RECON as vital pieces of every project that should be supported by employees from the top to the bottom. This evolved opinion helps keep employees safe, enables us to pursue more work and ultimately increases our bottom line. Now that is the type of evolution I can believe in!

Getting Plenty of Sleep

Remedial Construction Services, L.P.Getting plenty of sleep is a very important part of your personal safety. Most people need 7.5-8.5 hours of sleep each 24-hour day. Sleep loss built up slowly over several nights can be as harmful as sleep loss in one night. Both produce a decline in performance such as slower reaction times, failure to respond to changes, and the inability to concentrate and make reasonable judgments.
Research that tested a fatigued state from continuous hours of wakefulness against blood alcohol levels concluded that:
•    17 hours awake is equivalent to a blood alcohol content of .05
•    21 hours awake is equivalent to a blood alcohol content of .08 (the legal limit in Ohio)
•    24-25 hours awake is equivalent to a blood alcohol content of .10
In addition to fatigue caused by shortened periods of sleep, the quality of sleep during the day is not the same as during the night. People have a natural tendency to be awake during the day. Every person has a circadian rhythm - an internal biological time clock. This rhythm follows
Typically, in a 24-hour period, our alertness is reduced between the hours of 3:00 and 5:00 during the day and the night. So during night shifts, workers are fighting against their natural rhythm to stay awake at a time when they would naturally sleep.
How about you? Do you get enough sleep? It is important that you do for your safety and the safety of your coworkers.

Flashing Beacons & Reflective Vests

Remedial Construction Services, L.P.One of the RECON site requirements at the Vogtle Unit 3&4 jobsite is that all moving vehicles and equipment have flashing strobe lights.  While all RECON jobsites require personnel to wear safety/reflective vests, not all currently require the flashing beacons on equipment.  While a bright flashing beacon can even be seen during the day, the combination of the flashing beacon and reflective vests during dark or twilight hours has a tremendous effect.  The reflective tape on our safety vests really "pop" when they are around a flashing beacon.  It greatly improves the operator's ability to spot pedestrians in marginal or poor light.  The reflective tape can also be added to stationary hazards and moving equipment - providing a similar "pop" to highlight the hazards.  If working in anything but the best of light, it is recommended that other jobsite implement the use of the flashing beacons.

Safety

Road Conditions- Slippery When Wet

Remedial Construction Services, L.P.At some point in time every one of us at RECON will drive across slippery road conditions whether it is driving to work, driving during working hours or driving home. Dusty road conditions require a water truck to constantly water our haul roads throughout the work day. Freshly watered roads from a water truck or even a quick rain event can cause changes in road conditions and should alarm any driver to slow down, slippery when wet. When any driver is entering a freshly watered road or wet curve the driver's speed should automatically decrease.
