Abstract

A hazardous chemical is defined by the U.S. Occupational Safety and Health Administration as "any chemical that has been shown scientifically to be a health hazard (causes acute or chronic health effects) or a physical hazard (combustible liquid, explosive, flammable, etc.)". This federal agency estimates that there are about 5.7 lakhs chemicals in the workplace, with 50,000 being potentially hazardous. Considering that unplanned exposures and contamination that can occur at any time during manufacturing, transport, storage, usage, or disposal of these chemicals, inevitably, emergency physicians will, at some time, be responsible for the management and care of a hazardous materials patient. When managing a patient exposed to an industrial chemical, it is helpful to refer to the material safety data sheet. Here, specific physical and hazardous properties of a particular substance are described, including the risk for absorption after inhalation or dermal exposure, and the potential for systemic toxicity . But although the material safety data sheet will also include "first aid" recommendations, it is strongly recommended to consult with a medical toxicologist or a regional poison control center to discuss optimal, case-specific hazards, treatments, and dispositions. Some agents may result in delayed onset of symptoms that require at least 12 to 24 hours of monitoring. Also, contacting the regional poison control center facilitates accurate data collection and analysis of toxicologic exposures in the community.

Abstract

Systematic rock mass characterization is an integral part of rock engineering practices. In the present scenario several classifications are in used for rock mass characterization for tunnelling. The present paper discusses engineering geological investigations carried out for Punasa tunnel, a part of Narmada Sagar project. The horse shoe shaped tunnel is 3675.25 m long and 9 m in diameter. This straight and free flow tunnel has been constructed in basaltic lava flows erupted during Cretaceous to Eocene age, belonging to poor to fair rock mass rating (RMR) and extremely poor to good in tunnel quality (Q-system). The values of RMR and Q-system ranges from 29 to 74 and 0.0825 to 13.33 respectively.

Abstract

Obesity is a public health problem in the West ; it's prevalence in developing countries is generally believed to be low, but documented information in this regard is scanty.

Abstract

Obesity is essentially a disorder of energy balance.  It is the most common nutritional disorder of present day. In Great Britain obesity is probably more common among poor women than among rich and gives rise to more ill health than all the vitamin deficiencies put together. One of the surveys carried out in middle class urban population in Delhi revealed that every third woman above 40 years tends to be obese.

Abstract

Tools for measuring growth are simple and easy to use (weighing scale, measuring tape etc.) and are available in a community/family. However, no tool is available at present which may be simple, small, portable and easy to use for interpretation of anthropometric measurements collected at peripheral level. The KGAT card has been developed to fulfil this need.
