The new system to prohibit construction site trench soil shrinks

Geotechnical engineers in Loughborough University in England have been working on a new way to prevent catastrophic soil shrinks on construction sites, and landslides, occur naturally, but without notice. Good sensor system of the measure reducing sound behaviour of soil to predict when a landslide or trench is imminent, so as to take preventive measures before people are injured.

The new system works exactly the same way as the bending Rod a cracking noise which build up until it snaps. So that the movement of soil before rocks creates increasing rates of sound, "says investigator Neil Dixon of major projects.

"This has been known from the 1960s, but what we have been able to do so is a new capture and process this information in order to quantify the relationship between noise and soil displacement rates as it happens in real time-and therefore provides early warning."

The system has the potential to prevent their untold number of incidents, construction worker injuries and deaths from naturally occurring landslides in the world.

You can use any infrastructure-building tools

Develop system dual-use items. First because the system does not require a central computer, it may be placed in a developing country or anywhere where there is some potential for subsidence. The second system can be deployed to monitor the construction sites, mines and pits with potentially unstable slopes, built to maintain the road or rail embankments, fees or other infrastructure.

Network of cheap sensors should optical and/or acoustic alarms. They could even be set up to send text messages to the safety of the workplace disaster response personnel, giving them early warning which would enable them to evacuate the area, stop the workers or residents of cross field for unstable or take steps in order to stabilize the slope or trench.

Sensors act as microphones, noise in the subsoil, and sent to the central computer for analysis. Increased soil noises are known to predict imminent soil shrinks, but such information does not have practical application.

"Developing low-cost independent acoustic slope sensors is only possible in very recent times due to the presence of microprocessors that are fast, small and cheap enough for this task," said Dixon.

Commercially available sensor system may have to start the prevention of landslides and construction accidents early in the next two years.

OSHA asks directors to prohibit the injuries at work By crowd control

Occupational health and Safety Administration sent a letter this week directors of fourteen major retailers urging them to take steps now to prevent injuries to the customer and the worker during the Black Friday and other events, holiday sales. In 2008, the retail worker is trampled to death by the crowd during the event for sale Black Friday and OSHA says injuries associated with the crowd and related workers compensation claims are on the ground.

"Associated with the crowd injuries during special sales and promotional events have increased in recent years," said OSHA Assistant Secretary Dr. David Michaels in news letter version. The letter included OSHA fact sheet, called the "Crowd management safety tips for retailers.

"Many of these accidents can be prevented by the adoption of a management plan to the public, and this fact sheet provides retail employers with guidance for avoiding injuries during the holiday shopping season," said Dr. Michaels.

The beginning of the retail workplace safety during large events With good planning

OSHA recommends that employers plan in the future to prevent you from exceeding the dangerous and customer and employee injuries that come with it. The risks of overcrowding range from slipping and falling accidents or fires, falling goods to the crowd crush and attacks on the workers.

A plan should include, making sure that the proper emergency information, proper training, hiring of appropriate security and preparation of clear signage for store hours, the location of the sale of the main points, and where to leave the lines.

-Event's Setup

When you set up for the event, OSHA recommends:

Set up barricades or lifts, taking care that the line does not start right at the entrance of the store. Barricades the need to have regular rest periods, so that the customers were captured by if there is pushing To reduce the incentives behind. for customers push or jump to the line, the provision of tickets, wrist bands or other process for the login. Online auction of hot spots also could prevent unruliness. Make sure that the obstacles such as shopping carts, as well as any missiles are moved by the way. Ensure that the goods are the offspring do not fall. Be, make sure that ensure safe inputs for people with disabilities.

Prevent accidents and injuries during the event

Communication is key. Set Agent to update the restless customers how will move line and hot items will be sold--or are sold. The crowd control or security each entrance, including those that are not used. When the limit was reached for occupancy, prevent influx of new customers. Never block off ex.

In the event of 2008, when the worker is crushed to death by the crowd store has not used up the crowd control plan recommended by OSHA. This can prevent the customer and work accidents, claims for compensation of employees "and tragic events that can Mar holiday season.
