Aurora OSHA Construction News



July 9, 1999 Vol. 3, Issue 2

  1. There were 14 construction fatalities in Illinois in calendar year 1998. We have checked the Illinois data back to 1/1/80, and the 1998 total was the lowest in 19 years. Adding to this significance was the high volume of construction projects in 1998. The previous low number of Illinois fatalities was 18 in 1991. We thank the efforts of the contractors, unions, employees, and all safety professionals that made 1998 the safest year yet in Illinois.

  2. Knockout style boxes used at the end of flexible cords are being seen on many inspections. These are not allowed per NEC 300-11(a). The hazard is that the knockout could short across the hot screw and energize the metal box or the hot wire can come undone and energize the box.

  3. Several contractors using GFCI outlet boxes have been found with damaged extension cords and cord connected power tools. The GFCI did not work because the leads were improperly connected, and citations were issued for electrical hazards. The GFCI will only protect people if wired properly and in working order.

  4. We have cited three steel erection companies in the last month under 1926.105(a). The response for noncompliance has been the misconception that exterior falls are 30 feet for multi-story buildings. Several OSHA Review Commissions such as Adam Steel Erection and Williams set precedence in the early 1980's that the 25 foot rule applies to multi-story buildings. The 25 foot rule is in some Ironworker contracts.

  5. We have seen more hazardous flat roofing jobs than anytime in the past ten years. The lack of warning lines and the use of mechanical equipment near the roof edge top the list.

  6. Marking underground utilities has been a repeated problem. We have investigated trenching contractors hitting gas and electric lines, and in some cases it is unclear whether the utilities were mismarked or whether the contractor did not see the markings. JULIE (1-800-892-0123) has a color coding system for utilities:

                   Yellow - gas, oil, or petroleum

                   Red - electric, fire protection

                   Orange - communication, telephone, TV

                   Blue - potable water

                   Green - sewer

  7. Several general contractors have had difficulties with OSHA compliance on their first OSHA visit in construction. We have cited six different companies with 10 or more separate serious violations each. One GC had 21 violations. Generally, the inspections resulted from concerned people bringing photos of the site conditions to our attention.

  8. In March, a laborer narrowly escaped when the seven feet deep vertical wall trench collapsed on him. The Aurora Fire department was able to rescue him quickly as he was only partially covered with soil.

  9. In Belvidere, the Sunday night March winds blew down 40 foot high masonry walls. No bracing was used. Walls of this height must be braced during the construction process.

  10. The new 16 page directive on residential construction is out (STD 3-0.1A). It defines residential, setting the first two trusses, and wall building procedures. It is available on the OSHA home page > library > directives > type in residential as the search word.

  11. Three officials at Lemaster Steel entered guilty pleas that they made false statements to OSHA investigators in what caused the death of a worker in Mason, OH. The charges carry a maximum prison term of five years. The court has not determined the sentence as of this month.

  12. On March 18, 1999, the owner of Protech Construction was sentenced to 12 months incarceration for attempting to bribe an OSHA construction inspector in Illinois. He had been found guilty of two counts of violating 18 U.S.C. 201(b)(1)(a).

  13. The decision in R. P. Carbone Construction vs. OSHRC is the latest in a series of cases to hold a general contractor liable for safety violations of subcontractors, if the violations could have been easily detected and corrected. The superintendent of Carbone was the only person for the company at the site. He relied on the steel erector to comply and did not know the fall requirement for steel erection. The court said the general contractor may rely on the expertise of the subcontractor, but must "apprise itself as to what safety efforts the subcontractor has made." In addition, the court said the violations were in clear view and occurred on a regular basis. The ironworkers had worked for two weeks without fall protection.

Minimum of three citations were issued. Penalties reflect size, good faith and history discounts.

Comments about most penalized

Hoist area fall pro - Many roofers are not putting up guardrails in areas where hoisting is occurring. Roofers that comply have been using counterweighted guardrails.

Flat roof fall pro - Penalty is high due to company citation history and Willful classification for many.

Trench egress - Many trenches were over 7 feet deep and did provide for egress in the event of a trench collapse or other emergency.

Trench competent person - Many had trenching safety in the early 1990's and their knowledge of soil evaluation is eroding. The most recent example is a contractor telling us that the site had Class D soil. Class D soil didn't exist in the early 1990s, either.

Deficient safety training - See most cited.

Unsafe trench - Some of the problems have been with trenches 16 feet deep and only one box is used. This creates a cave-in into the box itself.

Six feet fall pro - See most cited.

General Duty Clause - See most cited.

Ladder extending three feet - See most cited.

Deficient safety program - See most cited.

Silica Dust Exposures from OSHA Construction Inspections in the Chicago Area

1996-1998

Information is drawn from an analysis of 82 inspections from the three Chicagoland OSHA area offices. 59 inspections had personal air sampling for a total of 136 employee air samples. This summary is condensed from a 57 slide PowerPoint presentation which has more detail on the operations.

Note that conclusions on exposures and respirators are based on limited numbers of samples and represent available info as of 2/1999. Conclusions are those of the author and have not received official agency review.

PEL = Permissible Exposure Limit


Heavy Construction Silica Dust Summary

Operation #Samples Likely Exposure Likely Resp Noise

Jackhammer dry 17 at PEL half mask 102-103

Jackhammer wet* 3 ? half mask

Concrete saw dry 4 > PEL half mask

Concrete saw wet 4 < PEL --

Lateral drill 9 > PEL half mask 97-104

Vermeer saw** 3 ? > PEL ? 96

Bobcat concrete 1 < PEL --

Shovel concrete 4 < PEL --


* Wet jackhammering overexposures occurred because no wetting was done on part of the project and the area was indoors/confined by a plastic containment.

**Vermeer saw overexposures are believed to be due to inadequate water spray due from clogged water line. Vermeer saw water tanks need regular treatment to prevent algae growth.


Masonry Silica Dust Summary

Operation #Samples Likely Exposure Likely Resp Noise

Tuckpointing 35 >> PEL full face* 92-106 or air line

Tuckpoint w/ vent 2 at PEL half mask

Block saw dry 9 > PEL half mask 92-93

Block saw wet 5 < PEL --

Brick saw dry 1 > PEL half mask

Brick saw wet 1 < PEL --

Stone cut dry 2 < PEL --

(stone was nonsilica "Renaissance" manufactured stone)

* Tuckpointing has consistently been the highest silica exposure in construction. Full shift silica exposures will typically range from 10X to 50X the Permissible Exposure Limit, which will require at least full face mask air purifying respiratory protection. Exposures can easily go above 50X the PEL, and at these levels air line respirators are needed. A work group to evaluate/develop engineering control measures is being put together.


Crossover/Special Operations Silica Dust Summary

Operation #Samples Likely Exposure Likely Resp Noise

Sandblaster 4 >> PEL blast resp 96-104

Sandblast potman 1 > PEL half mask 91

Abrasive blaster 7 > PEL blast resp

Abrasive potman 5 < PEL --

Sweep 5 can be > PEL half mask

Ceiling seam grind 1 > PEL half mask

Grind floor w/ vent 1 > PEL half mask

Tunneling (no silica) 4 < PEL --


Citation Summary

1.Overexposure/engineering controls

2. Correct respirator/respirator program

3. Silica hazard training

4. Hearing conservation program/protection

5. Silica safety program

6. Lead exposure (in tuckpointing and blasting)

Basic Conclusions

1. Dry operations: High likelihood of silica dust overexposure

2. Wet operations: Low potential for silica dust overexposure

3. Exposures are greatly increased by factors such as interior workplaces and confined locations (such as corners), even if control measures are utilized.
