Chain-Saw Gear and Tree Work Related Personal Protective Equipment

Summary: Alex Julius of the International Society of Arboriculture covers tree work related personal protective equipment: ear, eye, foot, head and chain-saw gear.

Chain-saw gear and ear-, eye-, foot- and head-wear act as tree work related personal protective equipment (PPE), according to Protect Your Assets (Part 1) in the October 2013 issue of Arborist News.

Alex Julius of the International Society of Arboriculture bases her information on arboreal safety standards in Canada, New Zealand, the United Kingdom and the United States. She collates the American National Standards Institute, the United Kingdom's Health and Safety Executive and The Best Practice Guidelines: Safety Requirements for New Zealand Arboricultural Operations. She describes proper choice, inspection, maintenance and retirement of accessories to protect ears, eyes, feet and heads and of attire to don prefatory to chain-saw operations.

Engineering controls such as power-saw chain-brakes, on-the-job equipment training and PPE express triple lines of defense against "loud noises, flying or falling objects, and tripping hazards."

Work-related hearing loss finishes first among occupational illnesses in the United States, with annual exposures at 22 million workers and yearly worker compensation at $242 million.

Foam-budded ear plugs, silicone-budded ear plugs and helmet-mounted earmuffs give Noise Reduction Ratings of 24 to 27, of 33 and of 21 to 26 decibels (dB). The British Standards Institute and the U.S. National Institute for Occupational Safety and Health have hazardous noise ceilings at 87 dB with protection and 85 without. Ear-wear is coordinated with such mandatory eye-wear as plastic-lensed, shatter-proof prescription or safety glasses that admit no direct light or projectiles and resist cracks and scratches.

Manufacturer's care instructions jog the memories of wearers of tree work related personal protective equipment about avoiding such solvents as gasoline and oils and cleaning properly.

Proper footwear keeps low profiles in discussions of tree work related personal protective equipment and high ratings as "one of the most properly used" of PPE.

Climbing, climbing on gaffers and spurs and ground-working respectively lead to wearing low-healed rubber-soled boots, high-heeled, stiff-soled lineman or logger boots and ankle-protected, strong-soled, toe-capped boots. Cracks and creaks mean that ear-, eye-, foot- and head-wear must be destroyed, and "replaced with new gear," so they "cannot be used by another person." Tree work related personal protective equipment needs to protect against helmet slippage, neck strain, things that go "Bump!" on the head and 2,200- to 22,000-volt conductors.

Chin straps, four- to six-point attachments and sweatbands and webbing respectively offer head gear wearers dislodging-, sliding- and slipping-proof protection, rear- or side-ratcheting mechanisms and suspension.

Chain-saw operations put chain-saw protective clothing (CSPC) in such forms as chaps, gloves, jackets and pants on the list of tree work related personal protective equipment.

Chain saws quit working upon contact with clothing made of jamming materials since Kevlar and Nomex clog the chain and the sprocket and jam the chain. Safety to life and limb requires that all buckles be buckled on cut-resistant chaps and that ankles be covered and wrapped by cut-resistant chaps and pants. CSPC should be destroyed when contaminants, dirt and oils resist removal, fibers show deterioration or matting and improper care uses fiber-degrading acids, bases and chlorine bleaches.

Engineering controls, training sessions and worker uniforms tap into concerns over worker and workplace safety since "PPE won't save your life if you don't wear it."

Storm Damaged Tree Clearances: Matched Teamwork of People to Equipment

Summary: Geoff Kempter of Asplundh Tree Expert Company ties savvy storm damaged tree clearances from lines and roads to the matched teamwork of people to equipment.

Storm damaged tree clearances from lines and roads are top priorities in Storm Response, Part 3: Effective Response to Large- and Small-Scale Storm Emergencies in the October 2013 issue of Arborist News.

Geoff Kempter of Asplundh Tree Expert Company bases successful large- and small-scale storm emergency responses upon coordinated, human and mechanical resource-matched teamwork of people to equipment. Successful storm responses call upon coordination by storm center personnel who "work entirely within the confines of a building, without ever actually seeing the crews working." They also depend upon crews that do not flinch from "collective efforts" or from "extraordinary amounts of time and hard work, sometimes at considerable personal sacrifice."

The action of mobilized crews and of storm centers emerge most pertinently and presciently when equipment, site, tree and weather data exist in accessible, up-to-date formats.

Planned, pre-coordinated, pre-mobilized matched teamwork of people to equipment furnishes municipality- and utility-operated storm centers with means, motives and opportunities for local deployments within two hours.

Local, small-scale storm emergency responses get general timelines of cleared lines and roads and of restored power and water within several hours to within two days. Having on-site safety specialists supervise crews "that are used to working together" helps "maintain order, discipline, and some semblance of normalcy" and reduce "risk of accidents." It is a contributor to timely completion of storm work, whose delineation from routine work involves more than "a single branch" breaking "on a breezy day."

Large- and small-scale storm responders jar citizen sensitivities by judging catch-up routine, or off-site restoration, work priorities over chipping storm damaged tree clearances and removing debris.

Quality monitors know of two criticisms when regional mutual assistance associations and storm centers pre-position a pre-storm planned, pre-coordinated, pre-mobilized matched teamwork of people to equipment.

Budgets and timelines lead storm responders to leave debris from storm damaged tree clearances on-site for chipping and removal by property residents or through public funds. Purportedly improving the "speed and effectiveness of the restoration effort by strategically moving personnel and equipment before storms strike" means earlier start-times for hopefully earlier end-times.

Early, large-scale mobilizations necessitate "costly" expenditures since "The size of responses to large storms has been increasing in recent years and can involve thousands of workers." They offer "advance preparations for areas" in projected paths of gradually developing hurricanes and winter storms or expensive rehearsals or huge waste "if forecasts are wrong."

Concerns about safe transits and temporary accommodations and for earlier end-times provide support for planned, pre-coordinated, pre-mobilized matched teamwork of people to equipment before storms strike.

Competition with evacuees for food and lodging quits being problematic through early mobilization into "tent cities" at strategic locations for centralized, comfortable, convenient economies of scale. The realization that "Every response is different and poses unique challenges" requires "[d]amage assessment teams composed of experienced utility, government, or contract employees" to mobilize first. Guidelines about "appropriate clothing, supplies, and information that may be required in unfamiliar work environments" and about "local work rules, customs, and hazards" strengthen all mobilizations.

Storm damaged tree clearances tend to be as economically, humanly, mechanically, physically and temporally non-disruptive as prescient planning, priority pre-coordinating and proactive pre-mobilizing take turns spotlighting.
