Hazard Identification & Risk Assesment in New Chassis Assembly Line

Chassis assemblies in any automobile industries are vulnerable to several hazards. In order to reduce the hazards we need to study and carry out Hazard Identification & Risk Assessment in New Chassis assembly to provide engineering solutions for preventing Accidents / dangerous occurrences and to evaluate the Risk. We have conducted many inspections and observation in the chassis assembly of an automobile industry. From our observations and findings we identified nearly 20 intolerable risks in the chassis line, for which the intolerable risks are converted into tolerable through small projects and those which cannot be converted are reduced through Safe Job Procedures (SJP). All the significant risks are controlled by Occupational Health & Safety Management Program, Standard operating procedures & Operation Control Procedure. From the project, the hazard is minimized or eliminated which ensures safety in the assembly line as well as the safety of workers.

Applicability of decentralized/centralized control procedures in distributed processing system development and operation

Distributed processing configurations have a distinct advantage over a centralized approach in their adaptability to a constantly changing environment. There are many other desirable attributes of distributed processing, including enhanced survivability (with the consequent increase in system availability), reconfigurability, and recoverability. Views have also been expressed on the desirability of a distributed philosophy of the preclusion of any centralized approaches. These enhanced capabilities necessitate effective production and operational control procedures in an environment which is by definition intricate and complex. It is therefore considered essential that all aspects associated with distributed processing system design, development, production, operation, and maintenance are subjected to an overall philosophy applicable to all its phases. To this extent, two models are proposed for use in the demonstration of the two philosophies which can be adopted, i.e. decentralized and centralized. Here the aim is to highlight the need, at the higher echelons of the control hierarchy, for a centralized philosophy for the effective coordination of locally identifiable subordinate control functions.

EFFECT OF HISTAMINE AND ESTROGEN ON THE GLYCOGEN CONTENT OF THE RAT UTERUS.

Intraluminal (IL) histamine and control saline solutions were administered to spayed rats to ascertain whether histamine could reproduce the uterine H2O and glycogen effects elicited by estrogen in 24 hr. Intramuscular (im) or IL injections of estrogen caused a 2–3% increase in H2O. This response was accompanied by a 3-fold increase in uterine glycogen. IL administration of histamine did not reproduce the water and glycogen responses evoked by estrogen. Free histamine produced no H2O imbibition, and the glycogen increase was only ⅓ of that effected by estrogen, while histamine dihydrochloride elicited neither a water nor glycogen response. Tissue sections showed that histamine-treated uteri had an increase in leukocyte content accompanying the small glycogen increase, while sections from estrogen-treated animals showed no leukocytic increase. Operational control procedures associated with the IL injections accounted for a 2% increase in H2O as well as a 20% increase in glycogen. Since, 24 hr after adminis...
