Alerting devices

While traveling, when the driver applies the brake, a continuous brake light is turned on, which does not catch the attention of the vehicle behind. Hence, the solution to the above problem can be given by developing an electronic module that converts ordinary brake light into an attention-getting visual alerting device. 

Are visual or vibrating alerting devices provided to supplement audible alarms Are visual alarms installed in all areas, including toilet facilities ... 

With plastics that decompose, there may be hazards such as personal bums or wounds and air contamination. Faulty controllers and/or freeze-off can cause the overheating situation from a burned out heater. Safety devices should be used that alert the plant when problems develop people have to be aware of these possible situations. Recognize that personnel injury in plants due to machinery represents 10% of all accidents (Fig. 8-77). 

Controllers and pumps have detectors and alarms that alert the nurse to various problems, such as air in the line, an occlusion, low battery, completion of an infusion, or an inability to deliver the preset rate When any problem is detected by the device, an alarm is activated to alert the nurse Potential complications in IV dierapy are die same as diose widi peripheral line... 

Historically, respirometers have been used for wastewater biodegradability evaluation. More recently [52], a mobile on-line respirometer was proposed and tested for monitoring the activated sludge inhibition due to industrial discharges in a sewer network. A derived portable device called a Baroxymeter [53], based on monitoring the respiration of a bacterial culture by pressure measurements and using respiration inhibition as a toxicity alert, was proposed for the rapid detection of the toxicity effect of some toxic substances. 

Craker et used Bel W, tobacco as a relatively simple monitoring device whereby interested citizens could develop some idea of the biologic severity of oxidant pollution in their community. There are problems with their study, but the concept is useful and might alert a community to potential pollution problems. 

A system for reporting fires and alerting the plant fire brigade and the municipal fire department should be provided. This system should be as simple as possible to minimize the potential for confusion in emergencies. The preferred design is a multiplex system that alarms in the control room or some other 24-hour constantly attended location and activates visual devices, such as strobes or beacons, and audible notification devices, such as a steam whistle, air horn, or tone generator. Complete systems are available from recognized vendors. 

Flash units and motor drives are potential ignition sources. In many cases, a gas test and hot work permit will be required before using a flash unit, motor drive, or video camera. Each specific use of flash devices may require authorization. Infrared gas detectors may also be set off by flash units. When using a flash even with permission, it is a good practice to take the time to warn and alert all personnel who could see the flash (or a reflection of the flash). This will preset... 

Levonorgestrel is used in the form of intrauterine devices, both as a contraceptive and to treat menorrhagia. They are effective, but critical reviewers continue to point to the need to be alert to the possible development of pain and hypermenorrhea, and to warn patients of the possibility of expulsion or perforation (46).
