Under construction bridge / flyover collapse in Varanasi on 15.05.2018 - reasons

As per reports, the bridge / flyover collapse leading to 18 deaths was due to issues involving design, quality, barrication, supervision. Proper records and checklist were not maintained making it difficult to ascertain the material used for concreting.  Pour card filling is to be done so that all details like area of work, ratio of cement, sand, water used, status of shuttering etc will be noted and signed by all concerned.

At least 8 students, 1 teacher injured in chemical fire at Hendersonville school

At least 8 students, 1 teacher injured in chemical fire at Hendersonville school: An official with the Hendersonville Fire Department said 17 students and one teacher were either triaged at the scene or transported to local hospitals.

During an experiment in lab by students to see change of flame colours of different salts, the incident happened. The incident appears to have happened to demonstrate rainbow flame by adding different salts to ignited ethyl alcohol. A flash fire occurred lasting 3-5 seconds.

In laboratories, will be working with known/unknown materials. The awareness on lab safety particularly in schools/colleges is generally low compared to industrial safety. Knowledge on properties of chemicals, methods to avoid hazards, control and mitigation measures, use of personal protective equipment, etc will help in avoid consequences from the work. Making safety principles as a topic in every subject let it be science / engineering / arts can help improving awareness.
