Audit your own working area against the hazards this exam names

short · 30 min · Objective 4.2

Task

Assess the place you actually work against each hazard class, and produce the controls list with what is missing. The value is that it is your bench rather than a diagram, and the gaps found are ones you can close this week.

Steps

  1. Write lab/safety/electrical.csv with header item,hazard,control_present,control_needed covering mains leads, extension leads, any uninterruptible supply, and every device you would never open.
  2. Write lab/safety/esd.csv with header control,present,where_used,exception covering wrist strap, mat, bags, edge handling and chassis contact -- and record in the exception column the one situation where a grounded strap is wrong.
  3. Write lab/safety/fire.csv with header class,what_burns,agent,nearest_extinguisher covering the classes this exam names, and record where the nearest suitable extinguisher actually is.
  4. Write lab/safety/lifting.csv with header item,estimated_weight,handholds,two_person,route_clear for the three heaviest things you might move.
  5. Write lab/safety/stop.md listing the circumstances in which you would stop work, and who you would tell.

Verify

awk -F, 'NR>1 && NF>=4 {n++} END {print n" electrical item(s)"}' lab/safety/electrical.csv
awk -F, 'NR>1 && NF>=4 {n++} END {print n" ESD control(s)"}' lab/safety/esd.csv
grep -Eic 'power supply|mains|near mains|high voltage' lab/safety/esd.csv
awk -F, 'NR>1 && NF>=4 {n++} END {print n" fire class(es)"}' lab/safety/fire.csv
grep -Eic 'never water|not water|co2|carbon dioxide|dry powder' lab/safety/fire.csv
awk -F, 'NR>1 && NF>=5 {n++} END {print n" lifting assessment(s)"}' lab/safety/lifting.csv
grep -Ec '^[-*0-9]' lab/safety/stop.md

Four electrical items, five ESD controls with the strap exception recorded, three fire classes including the electrical one with its agent, and three lifting assessments. The strap exception is the examinable detail and the one this lab exists to make you write down.

Notes

The nearest-extinguisher column is the one that turns this from an exercise into something useful. Most people discover they do not know, which is the finding.
