Jib Use On Energized Conductors How to comply

Jib Use On Energized Conductors How to comply with ANSI A 92. 2 2009 Standard (Insulated Jibs)

Are rubber hoses insulated? From: Carl Henning [mailto: Carl@mrea. org] Sent: Friday, December 04, 2009 3: 55 PM To: Nathan Boike Cc: Al Czeczok; Kurt Kumlin; Carolyn Sampson Subject: Are rubber hoses insulated? ? Nate, as I asked the question at the workshop yesterday. Are rubber hoses or blankets considered insulated? Nate the questions stems from my presentation on the Use Of Insulated Jibs. What the questions should say is, can a utility apply a rubber hose to a energized conductor, and then use their current no insulated jibs on their bucket trucks without using the insulated jib insert? ? The members at the conference and around the state sure seem to struggle with the idea of having to purchase the Jib Inserts for the purpose of doing energized work form an aerial lift truck. Nate could you please forward this question onto the folks that you mentioned that should be able to answer this for our members. Thanks Nate!!!!!

All cover-up equipment whether plastic or rubber line equipment, should NOT be regarded as insulation for personal protection. They have insulation but should NOT be considered primary personnel protection. In the ASTM standard F 968 though it relates to plastic, we recommend the same for rubber. i. e. “Brush contact only”. ASTM Standard, F 968 & F 712 states: “Plastic guard equipment covered by this spec is rated for momentary, or brush contact only. ” And the IEEE Standard 516 states:

Are rubber hoses insulated? From: Gingrass, John [mailto: John. Gingrass@Honeywell. com] Sent: Tuesday, December 08, 2009 11: 28 AM To: Nathan Boike Subject: RE: Are rubber hoses insulated? ? Nate, haven’t heard from the other party who thought might have some valuable insight. ASTM D 1050, Standard Specifications for Rubber Insulating Line Hose, places the responsibility of use/application on the user, e. g. 4. 3 “It is common practice for the user of this type of protective equipment to prepare complete instructions and regulations to govern the correct and safe use of such equipment”. Line hose are designed and intended to be installed on conductors in their natural and relaxed shape, any stress that deforms the line hose from its original relaxed shape can accelerate ozone cutting; which can reduce the product thickness. See ASTM F 478, Standard Specification for In-Service Care of Insulating Line Hose and Covers. And OHSA 1910. 137 Electrical Protective Equipment Yes there are considered “insulators” from incidental contact, they are temporary in their use and not designed to be left on the conductors for extended length of time. As noted in the language above, it’s the companies responsibility to determine if they would also require insulated jib inserts. Hope this is of help! John P.

Insulated Jibs from Hastings & Chance Carl: A couple updates. There are insulated jibs from Hastings and Chance. They are orange or white and foam filled, pinned, have a minor load rating, and must be bagged during travel just like a hotstick. They are tested as hotline tools, most customers test them annually with the boom. Another jib has been added by Altec. Its called a personnel jib extension and basically it is a bucket extension, not a load jib. It must be dielectric tested with the boom, and installed for the test. Dennis Ireland ATC

What is not providing insulation? • Jib • Covers • Winch line • Why? – Not Tested – Not maintained as insulating

What is providing insulation? • Upper boom when extended to the • Minimum extension label • Lower boom insert • Platform liner

Aerial Insulation • Category C and B: – Boom is secondary to primary protection such as gloves, sleeves, cover-up, and clearance distance. • Category A: – Aerial provides primary protection when following Bare Hand work practices.

High Resistant Upper Controls • High resistant upper controls are not required, do not have a rating, and are not part of the insulating system. • Decals must be provided indicating the HR controls. • “Do not provide protection in the event of electrical contact and are not a substitute for Minimum Approach Distances, cover-ups, rubber gloves and other personal protective equipment. ”

Decal 79238 at Lower Controls

Access Controls in Duel Platforms • Must be able to access controls in duel platforms • 4. 3. 3 Lower Controls: – Lower controls shall be readily accessible in all boom positions and shall provide a means to override the boom positioning upper controls provided the upper control system is intact. – The override mode shall maintain its function while unattended. The lower controls of insulating aerial devices shall be designed in such a manner that an operator is not placed in the electrical path between the aerial device and the ground.

Winch Control • 4. 3. 6 Winch Control – If the aerial device is equipped with a material handling winch at the upper boom, it shall have both upper and lower controls to operate the winch. – The lower control shall provide for overriding the upper control provided the upper control system is intact. – The lower winch control shall be accessible from the lower boom positioning controls.

Lower Controls • The operator cannot stand on the ground and operate the lower controls of an insulated machine. • 4. 3. 3 Lower Controls: – Lower controls shall be readily accessible in all boom positions and shall provide a means to override the boom positioning upper controls provided the upper control system is intact. – The override mode shall maintain its function while unattended. – The lower controls of insulating aerial devices shall be designed in such a manner that an operator is not placed in the electrical path between the aerial device and the ground.

Handling Energized Apparatus • When the boom tip jib and/or winch of a category B or C aerial device is used for handling energized conductors and apparatus, the energized conductors and apparatus shall be insulated from the boom tip with electrical protection devices that are rated, tested and maintained for the appropriate rated line voltage. • Boom tip jibs used in material handling on aerial devices shall be considered non-insulating unless the jib has been rated, tested and maintained for the appropriate line voltage.

Handling Energized Apparatus • Safety rules and work practices may vary significantly for different users, but one universal rule that applies is when jibs are used as a liveline tool with category B and C aerial devices, platform occupants(s) must use protective equipment such as gloves and cover-ups. • MUST HAVE INSULATED LINE LIFTING JIB IF WORKING WITH ENERGIZED LINES.

ANSI A 92. 2 2009 • Where in ANSI A 92. 2 does it indicate that insulated jibs must be used? – The purpose of the ANSI standard is to outline specific operational and design requirements. They typically do not address specific applications. For application requirements we should refer to the standard governing that operation, in this case, 29 CFR 1910. 269. – Following is the section related to this issue – Operations near energized lines or equipment. This is part of the section that address mechanical equipment operations.

OSHA Standards • "Operations near energized lines or equipment. " – 1910. 269(p)(4)(i) - Mechanical equipment shall be operated so that the minimum approach distances of Table R-6 through Table R-10 are maintained from exposed energized lines and equipment. However, the insulated portion of an aerial lift operated by a qualified employee in the lift is exempt from this requirement. – 1910. 269(p)(4)(iii) - If, during operation of the mechanical equipment, the equipment could become energized, the operation shall also comply with at least one of paragraphs (p)(4)(iii)(A) through (p)(4)(iii)(C) of this section.

OSHA Standards • "Operations near energized lines or equipment. " – 1910. 269(p)(4)(iii)(A) - The energized lines exposed to contact shall be covered with insulating protective material that will withstand the type of contact that might be made during the operation. – 1910. 269(p)(4)(iii)(B) - The equipment shall be insulated for the voltage involved. The equipment shall be positioned so that its uninsulated portions cannot approach the lines or equipment any closer than the minimum approach distances specified in Table R-6 through Table R-10.

OSHA Standards • "Operations near energized lines or equipment. " – 1910. 269(p)(4)(iii)(C) - Each employee shall be protected from hazards that might arise from equipment contact with the energized lines. The measures used shall ensure that employees will not be exposed to hazardous differences in potential. Unless the employer can demonstrate that the methods in use protect each employee from the hazards that might arise if the equipment contacts the energized line, the measures used shall include all of the following techniques:

OSHA Standards • "Operations near energized lines or equipment. " – 1910. 269(p)(4)(iii)(C)(1) - Using the best available ground to minimize the time the lines remain energized, – 1910. 269(p)(4)(iii)(C)(2) - Bonding equipment together to minimize potential differences, – 1910. 269(p)(4)(iii)(C)(3) - Providing ground mats to extend areas of equipotential, and – 1910. 269(p)(4)(iii)(C)(4) - Employing insulating protective equipment or barricades to guard against any remaining hazardous potential differences.

Standard • The application of the insulated jib can be considered as a method of addressing (p)(4)(i), (p)(4)(iii)(B), (p)(4)(iii)(C)(4). In other words, it becomes a component of the insulation in the boom and can provide insulation from the energized source, similar to using an insulated link stick between the winch hook and the line.

Something to Think About • I am sure there are other rules, regulations and interpretations that apply to this issue. However, I believe that the standard, rules and regulations are minimum requirements. If you are able to provide an additional source of insulation, that may reduce the reliance on grounding or barricading, while handling energized lines, then it improves the protection to the line worker and reduces the likelihood of injury from electrical contact with energized lines and equipment. From the risk management perspective, the use of the insulated jib reduces the need to rely on the compliance to a safety rule or practice. As you are aware, engineering the exposure out is a preferred method of risk control over administrative controls such as rules and practices that rely on the employee’s compliance. I believe the tool is effective, and the investment in the protective devices on each bucket truck is sound relative to the cost of electrical contact injuries, burns or fatalities.

Handling Energized Apparatus • If the winch line is used to lift energized apparatus, the energized apparatus shall be insulated from the jib tip with electrical protection devices that are rated, tested, and maintained for the appropriate line voltage. • The winch line shall not be considered as insulating. • For multi-phase lifting with conductor holders and a cross -arm, phase to phase protection shall be accomplished with a cross-arm that is rated, tested and maintained for appropriate line voltage. • MUST HAVE INSULATED LINE LIFTING JIB IF WORKING WITH ENERGIZED LINES.

From the Operator’s Manual What’s Insulated?

Where is Insulation

OSHA- Live Line Tool Test • 1910. 269(j) "Live-line tools. " • 1910. 269(j)(1) "Design of tools. " Live-line tool rods, tubes, and poles shall be designed and constructed to withstand the following minimum tests: • . . 1910. 269(j)(1)(i) • 1910. 269(j)(1)(i) – 100, 000 volts per foot (3281 volts per centimeter) of length for 5 minutes if the tool is made of fiberglass -reinforced plastic (FRP),

Why Minimum Extension • To maintain clearance for the platform and support structure in all boom positions. • To provide clearance for jib in all angles and positions. • That is the position it is tested

Why is the jib not considered Insulating? • It is used for lifting loads and subject to overloads. • It travels in and out in normal use, which causes tracking. • Is subject to damage • Short insulating length

Jib Structure

Non-Conductive Jibs • • Typically Hollow F/G Doesn’t meet the ASTM, OSHA or IEC stds Not normally tested Doesn’t have a periodic test requirement-As required by OSHA • Surface finish may or may not be acceptable for dielectric leakage • Impossible to test interior portion • No Certification label

Limitations in Letter, 4 th Paragraph • Jibs which have not been maintained, tested, stored and used per the requirements of Live Line Tool standards, and the other standards listed above should not be considered as a live line tool. • This may include jib sections that are normally stored installed on the unit and are routinely used for material handling. If the working jib does not meet the definition of a live line tool, it should only be used in conjunction with other rated live line tools such as a rated phase tree, or a rated link stick with the winch line for handling live conductors. • Safe work practices such as use of personal protective equipment, and maintenance of minimum approach distances are required when handling live conductors with the material handling system.

OSHA R-6 Table

Other Limitations, 5 th Paragraph • Please note that Altec® only dielectrically tests the boom(s) of rated insulated Aerial Devices or digger derricks to the applicable requirements of the above standards. We do not perform any tests on the vendor supplied jibs. It is important to note that when working from a category B or C insulated unit, the boom is not the operator’s primary source of insulation. The operator must use proper protective tools and equipment, rated for operations within the OSHA defined approach distances, as his/her primary source of insulation. Additionally, all metal components at the boom tip, including metal portions of the controls and jib structures, must be considered to be electrically connected. If an energized conductor or object touches any part of the boom tip, the entire boom tip must be considered energized. Similarly, if any grounded conductor or object touches any part of the boom tip, the entire boom tip should be considered grounded. The insulated portion of the boom can only isolate the operator from grounding through the boom and vehicle. The pole, cross arm and other hardware must be considered by the operator as grounded. The unit can’t protect a person from current between an energized conductor and any other conductor, ground or grounded equipment on or in contact with the pole including the neutral wire.
