Rubicon Engineering Flashcards
ANSI Z10
Occupational Health and Safety Mgmt Systems
safety through design
integrating hazard and risk analysis into design phase
Risk Assessment Process
- establish analysis parameters,
- Identify Hazards,
- determine the frequency and duration of exposure,
- Assess the severity of consequences,
- determine occurance probability,
- rank risks,
- develop solutions,
- follow up
hierarchy of controls
Eliminate, Substitute, Engineer, Admin, PPE
Elements of a Safety Plan
- Mgmt Commitment,
- Policy Statement,
- Safety Procedures,
- Safe Job Work Procedures,
- Job Safety Analysis,
project safety plan
identifies the entities and individuals responsible and accountable for implementing a safety plan
JSA
Job Safety Analysis,
Means of identifying and evaluating safeyty issues of a work task
benneficial occupancy
space can’t be occupied following contract work until it passes a fire inspection
how much load mst a fixed ladder withstand
250lb
CPM
Computeized Predictive Maintenance
furnace explosion
uncontrolled ignition of fuel in boiler furnace
safeguarding
any means of preventing people from contacting moving parts
device
control access to the point of operation
guard
barrier at the point of operation
enclosure
safeguards around a machine preventing access to moving parts
fencing
safeguard of a locked fence
safeguarding by location
make the hazard inaccesible
nip point
bite,
two or more mech parts moving in opposite directions
pinch point
like a nip point but not moving in opposite directions
point of operation
where material is worked on
shear point
area created by cutting movement of mechanical parts
built in safeguards
conform to the machine and come from manufacturer
barrier guards
prevent access to dangerous parts of machine
interlocking barrier guards
prevents operation unless guards are in place
automatic safeguards
prevents operator from accesing moving parts while in motion
automatic safeguards
prevents operator from accessing moving parts while in motion
PPE Program
- Policy,
- Select PPE,
- Training,
- Enforcement
Types of Protective Headwear
Type 1 - top impact, Type 2 - side and top impact, Class G - general service, Class E - Electrical Service, Class C - Conductive - no voltage protection
TF - Welding melts Contacts
False
characteristics of occupational hearing loss
always sensorineural,
usually not profound, lose different ranges
5 industrial health areas to keep sanitary
- potable water supply,
- sewage and garbage disposal,
- personal service facilities,
- food services,
- ventilation
4 components of occupational surveillance
- gathering info,
- analyzing data,
- disseminate data,
- intervention
3 Health Prevention Types
Primary Prevention - remove hazards before exposure,
Secondary Prevention - Conduct clinical testing to determine exposure level,
Tertiary Prevention - limit the damage of a disease
low volatage
600v and less
NFPA Hazard Diamond
red - flammable, blue - health hazard, yellow - instable, letter - special hazard, 4 - death, 3 - serious injury, 2 - residual injury, 1 - irritation, 0 - no hazard
NFPA Hazard Diamond
4 - flammable,
2 - health hazard,
3 - instable,
letter - special hazard
flash point
lowest temperature at awhich a flamable liquid will make flammable vapour
flammable liquid
- a liquid with a flash point lower than 60c,
2. a liquid with a flash point abouve 38 that is bulk transported
MPL, AL
Maximum Permissible Limit - engineering controls,
Action able Limit - Admin controls
dock boards bearing weight
4X max load
Inspecting hooks without latches
throat opening 15%
Elevator Classses
A - load is .25 of capacaity,
B - passangers trucks to capacity,
C - industrial trucks
rope
synthetic fibre is better
nylon fibre vs manila
nylon is 2X stronger and 4X elastic
polyester vs. nylon
polyester is less flexible but stronger
dynamic load
the forces on a roe when it is moving or swinging, stronger than static load
when to remove mesh slings from service
25% loss of diameter
HAVS
Hand arm vibration syndrome,
Reynaud’s, white finger
6 ways to avoid hand tool accidents
- PPE,
- right tool for right job,
- tools in good condition,
- grounded tools,
- use tools correctly,
- secure tools
double insulated tools
provide equivalent protection without third wire grounding
Biggest cause of chainsaw injuries
Kickback
Biggest Welding Hazard
Toxic Fumes
pulmonary gases
injures lungs and pulmonary systesm
non pulmonary gasses
doesn’t damage lungs but can displace O2,
ex C02
benign preumoconiosis
deposits of particulate matter in the lungs
ventilation rate for welding
general ventilation - 2000 cubic feet per minute per welder,
local exhaust - 100feet per minute
how to store cylinders
valve side up
GMAW
Gas Metal Arc Welding, MIG Welding
5 types of metal removing machines
turning, boring, milling, planing, grinding
EDM
Electrical Discharge Machine
press brakes
metal bender
process safety mgmtm
involve everyone in safety process by recognizing the risks of production
