Stuck In An Elevator? Do It Right: Sit Tight!

By: D&D Elevator

stuck in elevatorWhen people are riding an elevator, and it lurches to a stop between floors, often the initial gut response is to panic – especially among those who are claustrophobic – and what to do to most quickly to get out. Publicly-available accounts and data show that escape attempts can result in severe injury, sometimes fatal; for example, during a recent year, New York City’s Department of Buildings reported that 51 people were injured and five died when trapped riders tried to save themselves.

Municipal governments are undertaking campaigns to educate the riding public to the proper procedures during entrapment, such as New York City’s “Stay Safe - Stay Put” public awareness campaign – using broadcast ads, print ads, bus shelter messages and a public service video – to encourage riders to remain in stalled cars and wait for help,

As a service to building owners and managers, and other D&D Elevator Maintenance customers, D&D has prepared a comprehensive Safety Guide for Entrapped Passengers, which may be viewed online here and printed as a hard copy for provision to superintendents, co-op/condo boards, etc., for their review and appropriate distribution to tenants.

Time for a Cylinder Upgrade!

Cylinder Replacements

If today you are operating hydraulic elevators with Single-Bottom-Cylinders, this stands in violation of various state and city codes, as well as the requirements of ASME A 17.1-2000. For several years now, code requirements have called for the use of Double Bottom Cylinders and the replacement of older single bottom installations. These now outdated single-bottom cylinders were the industry-standard until 1971 when codes began to require going to Double-Bottom. Operating with Single-Bottom-Cylinders is risky, dangerous, environmentally unsound and inviting all manner of trouble.

And for good reason: Single-Bottom-Cylinders, by nature of their design, invite the possibility of catastrophic failure in the event that the bottom plate should rupture. Since these cylinders are positioned underground, below pit level, they are subject to sometimes harsh conditions leading to electrolysis and corrosion, which in turn can lead to fluid leaks. Leaking oil leaches into the environment and impacts the performance of the elevator, including possible sudden uncontrolled, downward lurching of the cab. In past years, numerous injuries and even fatalities have been reported as the result of such failures.

Alternatively, Double-Bottom Cylinders protect against bottom plate failures and ameliorate such hazards; these feature – in addition to the bottom plate – a bulkhead inside the cylinder, fashioned with a small opening allowing only a small amount of hydraulic fluid to escape, thereby reducing the risk associated with rapid downward descent of the cab. Today’s code also requires double-bottomed cylinders to be surrounded by PVC encasements, to ward off electrolysis and corrosion; this not only serves to protect the environment but also helps the property owner avoid unpredictable future downtime and expense for remediation of serious problems.

Bottom line, any Single-Bottom-Cylinders remaining in operation at this late date should be upgraded as immediately as possible, to head off a possible catastrophic failure – one which could be potentially and extremely expensive in terms of dollars, downtime and liability.
