Workers' Memorial Day — workplace inventions, safety milestones, labour history
1. What does Workers' Memorial Day on April 28 commemorate?
- Famous inventors
- Workers who died or were injured on the job
- Retirement milestones
- Labour union founders
An estimated 2.78 million workers die from work-related accidents and diseases every year worldwide — that's more than 7,600 people every single day.
2. What was the Triangle Shirtwaist Factory fire of 1911?
- A mining disaster
- A textile mill collapse
- A fire in a New York garment factory that killed 146 workers
- A chemical explosion
Most victims were young immigrant women. Exits had been locked to prevent unauthorised breaks. The tragedy led directly to dozens of new workplace safety laws and the growth of the International Ladies' Garment Workers' Union.
3. What colour is a standard hard hat typically associated with site managers?
- White
- Yellow
- Red
- Blue
Hard hat colours have specific meanings: white for managers, yellow for general labourers, blue for technical workers, and green for safety inspectors. The modern hard hat was invented in 1919 for workers on the Hoover Dam.
4. What does PPE stand for?
- Public Prevention and Education
- Personal Protective Equipment
- Professional Protection Enforcement
- Personal Prevention Equipment
The concept of PPE dates back to ancient times — Roman soldiers wore armour, and medieval blacksmiths used leather aprons. Modern PPE regulations weren't standardised until the mid-20th century.
5. Which industry has the highest rate of workplace fatalities in most developed countries?
- Construction
- Manufacturing
- Mining
- Agriculture
The 'Fatal Four' causes of construction deaths are: falls (33%), struck by objects (11%), electrocution (8.5%), and caught-in/between hazards (5.5%). Eliminating these would save over 500 lives per year in the US alone.
6. What is an MSDS (now SDS)?
- A mining safety device
- A Material Safety Data Sheet for chemicals
- A medical screening document
- A fire extinguisher rating
Safety Data Sheets contain 16 mandatory sections covering everything from first aid measures to disposal considerations. Employers must have an SDS for every hazardous chemical in the workplace.
7. What is RSI, a common workplace injury for office workers?
- Repetitive Strain Injury
- Risk Safety Index
- Respiratory System Infection
- Rapid Stress Indicator
RSI affects about 1.8 million workers in the UK alone. Using a mouse and keyboard for 4+ hours daily without breaks significantly increases risk. The condition was first identified in telegraph operators in the 1800s.
8. What major workplace reform limited child labour in British factories in 1833?
- The Factory Act
- The Mines Act
- The Employment Act
- The Health and Safety Act
The 1833 Factory Act prohibited children under 9 from working in textile factories and limited 9-13 year olds to 8 hours per day. Before this, children as young as 5 regularly worked 16-hour days.
9. What is the 'hierarchy of controls' in workplace safety?
- A management structure
- A ranking system for prioritising safety measures from most to least effective
- A list of emergency contacts
- An inspection checklist
The hierarchy goes: Elimination, Substitution, Engineering controls, Administrative controls, PPE. PPE is actually the least effective control — it should be a last resort, not a first response.
10. What was the Bhopal gas tragedy of 1984?
- A nuclear accident in Bangladesh
- A chemical spill in Pakistan
- A toxic gas leak at a pesticide plant in India
- A coal mine explosion in India
The Union Carbide plant leaked methyl isocyanate gas, killing an estimated 3,787 people immediately and up to 16,000 over time. Over 500,000 people were exposed. It remains the world's worst industrial disaster.
11. What is ergonomics?
- The study of electricity
- The study of work efficiency
- The science of designing workplaces to fit the worker
- A type of exercise programme
Good ergonomic design can reduce workplace injuries by up to 60%. The field originated during WWII when it became clear that poorly designed cockpits were causing pilot errors and crashes.
12. What does a yellow warning sign with a black exclamation mark indicate?
- General caution/hazard
- Fire risk
- Electrical danger
- Biological hazard
The international hazard symbol system uses shapes and colours: triangles for warnings, circles for mandatory actions or prohibitions, and squares for information. These symbols cross language barriers and save lives.
13. How often should fire extinguishers typically be inspected in most workplaces?
- Every week
- Every 6 months
- Every month
- Every year
Monthly visual inspections check that extinguishers are accessible, charged, and undamaged. Full professional servicing is typically annual. The average person has just 2 minutes to use an extinguisher before a small fire becomes uncontrollable.
14. What is a 'near miss' in workplace safety terminology?
- A failed safety inspection
- An incident that could have caused harm but didn't
- A minor injury
- A close deadline
According to Heinrich's Triangle theory, for every serious workplace injury there are approximately 29 minor injuries and 300 near misses. Reporting and investigating near misses can prevent future serious accidents.
15. Which organisation sets and enforces workplace safety standards in the UK?
- WHO
- OSHA
- HSE
- ILO
The Health and Safety Executive (HSE) was established in 1974 following the Robens Report. Since its creation, workplace fatalities in the UK have fallen by over 85%, making British workplaces among the safest in the world.
