- http://www.fairwarning.org/2010/08/after-nearly-a-decade-osha-adopts-rules-to-prevent-crane-deaths/ Dr. David Michaels of OSHA said in a statement.
- Consultant Brad Closson, vice president at the San Diego office of the North American Crane Bureau, explained that losses stemming from a crane failure do not stop with the incident itself. "Personal experience tells me that after a crane incident, productivity drops dramatically," said Closson, who spends much of his time doing crane accident investigations. "Everyone is focused on the horror of what has just occurred." http://www.setonresourcecenter.com/Alerts/nov/nov_2002b.htm
- From a safety perspective, perhaps the most fundamental change in crane technology over the past three decades has been the shift from mechanical cranes with brakes and friction the operator could "feel" to hydraulic cranes.
- 1926.1427 (a)(4) Whenever operator qualification or certification is required under § 1926.1427, the employer must provide the qualification or certification at no cost to operators who are employed by the employer From the preamble - it is reasonable that employees and independent crane operators, who have already been sufficiently trained in crane operation and may have many years' experience, certainly need no more than a short preparation to successfully pass the crane operator certification tests. The issue of when a person flunks, does the employer pay for a retest?
- Articulating cranes (such as knuckle-boom cranes); Crawler cranes; Floating cranes; Cranes on barges; Locomotive cranes; Mobile cranes (such as wheel-mounted, rough-terrain, all-terrain, commercial truck-mounted, and boom truck cranes); Multi-purpose machines when configured to hoist and lower (by means of a winch or hook) and horizontally move a suspended load; Industrial cranes (such as carry-deck cranes); dedicated pile drivers; service/mechanic trucks with a hoisting device; Crane on a monorail; Tower cranes (such as fixed jib, “hammerhead boom”, luffing boom and self-erecting); Pedestal cranes; Portal cranes; Overhead and gantry cranes; Straddle cranes; Side-boom tractors; Derricks; And variations of such Equipment . (c) Exclusions. This subpart does not cover 1926.1400 (c)(8) Powered industrial trucks (forklifts), except when configured to hoist and lower (by means of a winch or hook) and horizontally move a suspended load
- * Subject to State & Local requirements and whether or not the military/state training meet accredited requirements.
- Under § 1926.1427(b)(1)(i), for a testing organization to become accredited, the accrediting agency must determine that the testing organization's written testing materials, practical examinations, test administration, grading, facilities/equipment and personnel meet industry recognized criteria
- When assembly / disassembly could get within 20 foot of a power line either; Shut off and ground Maintain the 20’ clearance including the meeting, non-conductive taglines insulators etc plus A proximity alarm, dedicated spotter, warning device or insulating link Or verify with utility exact voltage and use a table for safe distances
- First, current policy recognizes other types of insulating barriers besides the type to which the Committee referred. [57] OSHA also recognizes goal-post-type barriers and, in certain limited circumstances the insulation on insulated power lines operating at 480 volts or less. See, e.g., letters of interpretation dated February 8, 1994, to Mr. Ivan Blood ( http:// www.osha.gov ) and August 9, 2004, to Mr. Mathew McFarland ( http:// www.osha.gov ). Second, the Agency does accept barriers that protect against brush contact under limited circumstances. See, e.g., letter of interpretation dated February 8, 1994, to Mr. Ivan Blood ( http:// www.osha.gov ).Show citation box It is similarly inappropriate to require a showing that it is infeasible to deenergize and ground the lines or relocate the lines under paragraph (b) of this section for subpart V work. Subpart V provides for deenergizing and grounding as an alternative to live line precautions, but it also recognizes that subpart V work may take place on live lines to avoid power disruptions to the utility's customers and includes precautions for such live line work. Thus, subpart V leaves to the utility employer the discretion to decide whether to deenergize and ground without the need for an infeasibility determination, and OSHA concludes they should continue to have this same discretion under this final rule. OSHA also notes that paragraph (b) of this section requires the employer to consult with the utility owner/operator before deciding that it infeasible to deenergize and ground the lines or relocate them, and it would be anomalous to apply this provision where the utility owner/operator is itself the employer.
- Employer Procedures Developed by a qualified person Designed to: • Prevent unintended dangerous movement to prevent collapse • Provide adequate support and stability during A/D process • Minimize employee exposure to unintended movement or collapse
- The Assembly/Disassembly supervisor is responsible for addressing these plus:
- 1926.1402 (b) The equipment must not be assembled or used unless ground conditions are firm, drained, and graded to a sufficient extent so that, in conjunction (if necessary) with the use of supporting materials, the equipment manufacturer's specifications for adequate support and degree of level of the equipment are met
- Competent person: “Means one who is capable of identifying existing and predictable hazards in the surroundings or working conditions which are unsanitary, hazardous, or dangerous to employees, and who has authorization to take prompt corrective measures to eliminate them.” Qualified person: “Means a person who, by possession of a recognized degree, certificate, or professional standing, or who by extensive knowledge, training and experience, successfully demonstrated the ability to solve/resolve problems relating to the subject matter, the work, or the project.”
