Safety precautions are neccessary. Incorrect use of electricity can cause electric shock and fire. Both are life threatening and a real risk.
Appropriate safety precautions for a laboratory vary widely depending on the kind of lab, the kind of work performed in the lab, and whether it is an educational or working lab. For example an organic chemistry lab requires precautions that are substantially different for those needed in an electrical engineering lab.
Usually they are handled by gripping the neck of the flask from the side. Get in the habit of never allowing you hand to be over the opening in the neck. Sometimes the fumes coming out through the throat of the flask can be hot or corrosive and burn you.
Besides not dropping heavy weights onto your body, or developing a strain/sprain from handling heavy materials, lead is a toxic metal that is a health hazard. It enters the body by ingestion (eating it) or respiration (breathing lead dust). Sanitation is a first line of defense- use gloves, and wash any exposed skin before eating, drinking, smoking, or applying makeup. Clothing contaminated with lead should be laundered separately from other clothing to prevent cross contamination. To control respiratory hazards, avoid creating lead dust. Engineering controls may be used to contain lead dust, or prevent it from becoming airborne (using paint stripper rather than sanding old paint, etc). Respiratory protection may be needed in some cases. Where there is a severe exposure to lead, workers may need to be in a medical monitoring program, where blood samples are analysed to insure workers are not overexposed to lead.

No special precautions are needed for handling Uranium 234, only normal chemical laboratory procedures. But U234 is rare and without specific use, so there is no need to work with this isotope.
It should isolated from underground water and isolated from rivers and drinking water. It should be away from expected earthquake
There are no major precautions for access during emergency procedures.
The Coal Handling Plant is needed in the coal handling process.
1.do not use bare hands while rescuing the person as it may infect the wounds. 2.be extremely careful about handling the victims body as it is fragile. 3.keep accomodities like stretchers,glucose bags etc.and the necessary first aid while handling such situations.

There are no precautions necessary for travelling to Australia, beyond the usual basic safety precautions one would take within one's own country. No vaccinations are needed.

A radioactive source was needed for ions to get trapped by the smoke particles and conduct less of an electric field. Several sources were tried before Americium was settled upon.
