Crystalline Silica: Not Just Fun in the Sand Revisited

Stephen Badger 2014Posted by Stephen Badger, CSP, OHST

Although summer is now nothing but a distant memory and the beaches will be empty for months to come, we should remember that respirable crystalline silica is a major health hazard for those that are exposed to it.  November is Lung Cancer Awareness Month, so it seems appropriate to review recent OSHA enforcement policies regarding crystalline silica.

As a reminder, crystalline silica is the second most common mineral in the Earth’s crust and is found all over the world even in the sand on our beaches. Silica actually can be in one of three forms; Quartz, Cristobalite, and Tridymite. Quartz is the most common form and is found in many of our everyday building materials.

When workers chip, grind, saw, or cut materials that contain silica, small “respirable” pieces can be made that can be easily inhaled. While larger pieces of silica can become filtered out in our nose and trachea, respirable silica can continue down our respiratory tract and become lodged in our lungs. These microscopic particles are responsible for the health hazards associated with exposure the silica.

Between 1968 and 1992 approximately 20,000 employee deaths were associated with exposure to silica in the workplace. These death were caused by silicosis (a scarring of the lung tissue caused by silica), lung cancer, and kidney disease.

Silicosis is the most common disease associated with silica exposure. It can take 15-20 years to develop (chronic) with low to moderate exposures to silica, but it can take only a few months to a couple of years of high exposures to develop acute silicosis.

Because of the increased understanding of the health effects of exposure to silica, OSHA introduced a new standard on September 23, 2017 beginning with compliance assistance in lieu of full enforcement.  On October 19, 2017 Compliance Safety and Health Officers began full enforcement of 29 CFR 1926.1153 that contains many new requirements for the protection of employees who are exposed to silica:

  • The Permissible Exposure Limit (PEL) has been reduced to 50 ug/m3 for an eight hour Time Weighted Average (TWA).
  • Airborne exposures of silica to the Action Level of 25 ug/m3 triggers closer employee monitoring to ensure that the PEL is not exceeded.
  • Table 1 in the standard addresses specific work tasks with potential exposures to silica and the engineering and work practice controls required to reduce airborne particles.
  • New medical monitoring criteria for those employees exposed above the PEL.

In June 2018, OSHA’s General Industry silica regulation, 29 CFR 1910.1053, will become law and require many of the same worker protections as in Construction. Two notable exceptions in this standard:

  • Employers have to include employees in their silica exposure control program if they exposed above the crystalline silica Action Level for 30 or more days per year
  • Employers have 15 days to notify effected employees of the results of any air monitoring

Vehicle Lift Safety

LaCrossPosted by Jeremiah LaCross

Vehicle lifts are widely used throughout the automotive service industry and are very effective pieces of equipment when proper safety procedures are followed. There are different types of lifts which include two-post surface mounted, four post, in-ground, mobile, etc. Each type of lift has specific safety procedures for safely lifting the vehicles.

Since 2007, OSHA has conducted several automotive lift inspections, 11 of which resulted from fatalities. Click here to read more about one of these fatalities.  According to the Consumer Product Safety Commission, a total of 15,000 workers were treated in hospitals for automotive lift, jack or jack stand injuries.

What are the employers responsibilities?

  • Ensure that annual inspections are conducted by a qualified lift service company.
  • Ensure daily inspections and proper operation of arm restraints, locking devices, shut off devices for over travel, lift controls, drive chains, wire rope, hoses, wiring, hydraulic leaks, floor cracks, and anchors.
  • Ensure that all users of the vehicle lifts are properly trained in the safe operation and maintain the training logs.
    • Many lift service companies provide training as an additional value added service.
  • Maintain all vehicle lift maintenance and/or repair logs.
  • Ensure a lockout/tagout program is in place for all vehicle lifts in the facility.

What are the operators responsibilities?

  • Immediately report any unsafe conditions identified during the daily inspection to your Supervisor.
  • Never use a vehicle lift without receiving proper safety training.
  • Always utilize all safety features per the manufacturer’s instruction.
    • Example: ALWAYS lower the lift onto the safety locks before proceeding to work under the vehicle.
  • Become familiar with vehicle lift points, which can be found in the service manuals and/or manufacturer’s instructions.
  • ALWAYS inspect the vehicle prior to lifting. Certain conditions may change the vehicles stability such as snow or ice buildup in a truck bed, a plumbing or mechanical van with excessive weight in the back.  
  • Maintain a clean work area to avoid slip or trip hazards that can cause injury.

What are some common violations that we see?

  • Failure to properly lower the vehicle onto the safety locks. This places the entire load force on the hydraulics, which creates a significant crush-by hazard should the hydraulics fail.
  • Failure to conduct vehicle lift safety training for all operators.
  • Failure to retain the proper documentation of the following:
    • Safety training.
    • Maintenance/repair logs.
    • Lift inspections.

More information regarding vehicle lift safety is available from the Automotive Lift Institute and the Automotive Equipment Technical Institute.

Office Ergonomics is Music to My Ears

LarochellePosted by Greg LaRochelle, WCP®

As a fan of most music genres, especially alternative and classic rock, several song titles come to mind that I believe fit nicely with the topic of office ergonomics.  Unlike the Billboard Top 100, these 12 songs are not ranked in any particular order but rather correspond to sound advice on avoiding repetitive stress or cumulative trauma injuries related to computer use.  And with a one and a two and a three…

  • Mighty Mouse by Tesla from the album Into the Now released in 2004: While the mouse is a mighty input device, it can be a source of significant stress to the wrist, forearm, elbow, and even the shoulder and lateral side of the neck. Keep the mouse in close proximity to the keyboard within short reach.  Consider using a vertically designed mouse to approximate a more neutral forearm posture.  Navigate into the mouse properties via the control panel to speed up the pointer motion speed from the default halfway setting.  You won’t have to wrestle with the mouse so much to move the cursor arrow across the monitor screen.

  • Codes and Keys by Death Cab for Cutie from the album Codes and Keys released in 2011: Use shortcut keys as a quicker and easier method of navigating and executing commands in software programs. Keep the keyboard flat on the work surface to minimize hand/wrist extension.  Consider using an ergonomic keyboard for a less constrained typing posture.

  • The Big Screen by Travis from the album Where You Stand released in 2013: Monitor technology has come a long way from the days of the 15 inch CRT design. Large 24 inch screens help to spare the eyes from straining to see the display items.  When using two monitors, keep the primary monitor front and center or if both are shared virtually equally, mate them symmetrically with the centerline of the keyboard with roughly a 30 degree angle between the two.

  • Far Away Eyes by The Rolling Stones from the album Some Girls released in 1978: To avoid a forward head posture (anterior head carriage) with torso flexion, position the monitor(s) within a range of 18 to 24 inches from your eyes. To reduce eyestrain, apply the 20/20/20 rule (for every 20 minutes of fixed gaze on the monitor screen, look at an object about 20 feet away for 20 seconds).

  • Hold Your Head Up by Argent from the album All Together Now released in 1972: Depending on prescription eyewear, adjust the height of the monitor(s) to promote a neutral, upright head posture.  A ream of paper (2 inches thick) or two inserted under the base of the monitor is a frugal way to increase the screen height.  Use a document holder or inline adjustable angle copy stand to minimize downward head tilt.

  • The Phone Call by The Pretenders from the album Pretenders released in 1980: The phone should be positioned on the side of the keyboard and monitor for the hand favored in grabbing the handset to prevent a crossover reach. Use a phone headset if cradling the handset between the neck and shoulder is a constant and prolonged task when conversing with the party on the other end of the line.

  • Someone Keeps Moving My Chair by They Might Be Giants from the album Flood released in 1990: Ah, the shared chair that someone adjusts to their own liking. Get to know the chair’s adjustment features such as backrest tilt and height, seat pan height, depth, and angle, lumbar support, and armrest movement to restore it back to a comfortable fit.

  • Blinded by the Light by Bruce Springsteen from the album Greetings from Asbury Park, N.J. released in 1973: Ambient light in the office environment is oftentimes too much, resulting in decreased contrast on the monitor screen. This can lead to the unconscious behavior of squinting and leaning forward straining the eyes, neck, and shoulders.   A small desktop task lamp can provide adequate illumination in a half-light ambience.   

            MEMIC Safety Net Blog: See More with Less? Yes! posted in 2011

  • Within Your Reach by The Replacements from the album Hootenanny released in 1983: Applying the neutral zone principle to workstations establishes a boundary of 18 to 24 inches for the placement of most frequently used items such as the keyboard, mouse, phone, and pen & pencil container.  Less frequently used items such as reference books, desk organizers, and electric calculators should be situated within a secondary zone of 24 to 36 inches and slid closer when needed.

  • Get Up, Stand Up by The Wailers from the album Burnin’ released in 1973: Prolonged sitting leads to static muscle activity with reduced blood flow to the affected body area. A micro-break every 20-30 minutes in a standing position with stretching can help to reinvigorate fatigued, contracted muscles.   Consider a desk mount sit/stand unit or height adjustable workstation for a more dynamic work routine.   Remember the best posture is the next posture!

  • In the Lap of the Gods by Queen from the album Sheer Heart Attack released in 1974: Laptop use induces a constrained upper body posture with significant downward head tilt. For prolonged use, connect a mouse and keyboard (wireless or corded) and elevate the laptop on a stand or stack of paper reams to view the screen with a neutral head position.
