Me"hani"al Hazards (SHA e)plains that mechanical hazards occur in
three basic areas* at the point +here +ork isperformed, in the po+er transmission apparatus andin other mo'in$ parts
-ork points include areas +here cuttin$, borin$,
shapin$ and formin$ take place. %o+er transmissionareas are /y+heels, belts, pulleys, couplin$s,connectin$ rods, chains and $ears, accordin$ to(SHA. (ther mo'in$ parts in machinery consist ofrotatin$, reciprocatin$, trans 'ersin$ and feedin$mechanisms.
#rush points are also mechanical hazards in +hicht+o objects mo'e close to$ether. These mechanicalhazards can easily crush limbs, n$ers and bones.#rushin$ incidents can also lead to death in certaincircumstances.

Controls for Me"hani"al
Hazards
If hazard is not essential to the e)perimentor project, eliminate it all to$ether oren$ineer it out
If it is not possible to eliminate the hazard,$uard it
If it is not possible to $uard it, must rely ontrainin$ and personal protecti'ee2uipment

Ele"tri"al Hazards
&lectricity is a safe, clean and 2uiet method of
transmittin$ ener$y. Ho+e'er, this sourceof ener$y +hen accidentally brou$ht into contact +ith
conductin$ material, such as people, animals or metals,permits releases of ener$y +hich may result in serious
dama$e or loss of life. #onstant a+areness is necessaryto a'oid and pre'ent dan$er from accidental releases of
electrical ener$y

&lectric shock is the
con'ulsi'e reaction by thehuman body to the /o+ ofelectric current throu$h it.
&lectric burns are usually
more se'ere than thosecaused by heat, since theycan penetrate deep intothe tissues of the body.
The shock can beproduced by lo+ 'olta$es,hi$h 'olta$es or li$htnin$.
The burns can bedetermined by theduration of contact andthe electrical resistance ofbody tissue.
