1. PURPOSE
This Standard Operating Procedure establishes the minimum requirements for the safe manual handling, crane-assisted lifting, and movement of glass and mirror on the Rossen Glass & Mirror Ltd. shop floor. It covers all glass and mirror products processed at the facility, including raw stock, cut pieces, polished and mitred pieces, and tempered glass. The goal is to protect employees from lacerations, crush injuries, and musculoskeletal strain, and to prevent product damage.
2. SCOPE
This SOP applies to all shop floor employees who handle, move, lift, or position glass or mirror at any stage of fabrication. It covers the following materials:
| Material | Thickness Range | Edge Condition | Notes |
| Float glass |
2 mm – 12 mm |
Raw / cut, polished, mitred |
All standard handling rules apply |
| Tempered glass |
5 mm – 12 mm |
Polished or mitred (pre-temper) |
Cannot be cut after tempering — handle with extra care; spontaneous breakage risk |
| Mirror (silver) |
3 mm, 5 mm |
Raw / cut, polished |
Backing coating is fragile — never lay face-down on abrasive surfaces |
3. RESPONSIBILITIES
All Shop Floor Employees
- Read, understand, and follow this SOP before handling any glass or mirror.
- Wear required PPE appropriate to the edge condition of the glass being handled (see Section 5).
- Use the overhead crane and vacuum lifter whenever the piece is within crane coverage and the lift warrants it.
- When in doubt about whether a piece is safe to handle alone — ask for help. There is no expectation to lift beyond personal comfort or capability.
- Report any near-miss, cut, breakage, or equipment fault to a supervisor immediately.
Supervisor
- Ensure all employees are trained and have reviewed this SOP before working on the shop floor.
- Maintain the overhead cranes, vacuum lifters, and all handling equipment in safe working order.
- Investigate all incidents and near-misses and implement corrective actions.
4. HAZARDS & RISK SUMMARY
| Hazard | Potential Harm | Controls |
| Raw / cut glass edges | Severe laceration | Cut-resistant gloves mandatory; handle on edge |
| Glass breakage during handling | Laceration, eye injury from shards | Safety glasses highly recommended; controlled movement; no rushing |
| Tempered glass spontaneous break | Shattering into small fragments | Safety glasses highly recommended; aware of breakage pattern; safe stance |
| Overexertion / heavy lift | Back strain, muscle injury | Use crane; ask for help; lift with legs not back |
| Glass falling or tipping | Crush injury, severe laceration | Maintain firm grip; use A-frame racks; never lean unsupported |
| Mirror backing damage | Product loss; sharp edge exposure | Protective padding; never face-down on abrasive surfaces |
| Vacuum lifter failure | Glass dropping from height | Pre-use inspection; weight limit check; no one under suspended load |
| Pinch points during crane moves | Crush injury to hands or feet | Clear path; steel-toed footwear; hands clear of pinch points |
| Glass dust / fine particles | Eye and respiratory irritation | Safety glasses recommended; avoid grinding without mask |
| Slippery floor from glass dust | Slip and fall | Clean up glass dust and cullet immediately |
5. PPE & GLOVE REQUIREMENTS BY EDGE TYPE
The required level of hand protection depends on the edge condition of the glass or mirror being handled. Steel-toed safety footwear is mandatory at all times on the shop floor. Safety glasses and hard hats are highly recommended and should be worn whenever there is a risk of flying debris or overhead hazard.
| Edge Condition | Examples | Gloves Required? | Recommended Glove |
| Raw / cut edge (unfinished) |
Stock glass from cutter or scorer; cut-to-size pieces before any edge work |
YES — Mandatory |
Cut-resistant, ANSI A4 minimum |
| Seamed edge (arrised) |
Lightly ground edge to remove sharpness; not fully polished |
Highly Recommended |
Cut-resistant, ANSI A4 minimum |
| Polished edge |
Machine- or hand-polished flat, pencil, or bevelled edge; smooth to the touch |
Highly Recommended |
Light cut-resistant or leather palm |
| Mitred edge |
Ground and polished angled edge (e.g. 45° mitre for frameless corners) |
Highly Recommended |
Light cut-resistant or leather palm |
NOTE: Gloves are highly recommended for seamed, polished, and mitred edges even though they are not mandatory. These edges are safer than raw glass but can still cause cuts, particularly on large or heavy pieces where grip and control are more demanding. When in doubt, glove up.
⚠ WARNING: Steel-toed safety footwear is MANDATORY on the shop floor at all times. Safety glasses and hard hats are highly recommended — wear them whenever there is any risk of debris, breakage, or overhead movement.
6. LIFTING DECISION — CRANE, TWO-PERSON, OR SOLO
Rossen Glass & Mirror Ltd. operates two overhead cranes, each fitted with a vacuum lifter, covering the majority of the shop floor. The crane is the preferred method for all lifts where it is practical to use it.
Use the overhead crane and vacuum lifter when:
- The piece is within the coverage area of either crane.
- The piece is large, heavy, or awkward enough that carrying it manually presents a strain or control risk.
- The destination requires the piece to travel more than a short distance across the floor.
- The piece is tempered glass — tempered glass should be crane-lifted wherever possible due to spontaneous breakage risk during manual handling.
Two-person handling applies when:
- The piece is outside crane coverage and is too large or heavy for safe solo handling.
- An employee has any doubt about their ability to control the piece alone — when in doubt, ask for help.
- The piece must be manoeuvred into a tight or awkward position where a second person is needed for control.
Solo handling is acceptable when:
- The piece is small and light enough that the employee is confident they can maintain full control throughout the move.
- The path is clear and the destination is close.
- The employee has the experience and comfort level for the specific piece and move.
NOTE: There is no fixed weight threshold at Rossen Glass & Mirror Ltd. — experienced employees use their judgment. The guiding principle is simple: if you are unsure, ask for help. No piece of glass is worth an injury.
7. MANUAL HANDLING PROCEDURE
Whether solo or two-person, the following principles apply to all manual glass handling on the shop floor.
1
Assess the piece before touching itBefore picking up any glass or mirror, identify the edge condition (raw, seamed, polished, or mitred), the approximate size and weight, and any chips, cracks, or damage. A damaged piece is significantly more likely to break during handling — proceed with extra caution or use the crane.
2
Don appropriate PPEConfirm steel-toed footwear is on — this is mandatory. Put on the correct gloves for the edge condition as per Section 5. Safety glasses and a hard hat are highly recommended and should be worn whenever there is any risk of breakage or flying debris. Roll up loose sleeves.
3
Plan the move before liftingKnow where the piece is going before you pick it up. Clear the path of any obstacles, other glass, tools, or debris. Confirm the destination (rack, table, or machine) is ready to receive the piece before you begin moving.
4
Always carry glass on edge — never flatGlass and mirror must always be carried vertically, on edge. Carrying flat dramatically increases the risk of the piece flexing and breaking under its own weight, particularly for thin glass (2–4 mm) and large panes.
5
Grip positionFor raw or seamed edges: grip the top edge with gloved fingers curled over, and support the bottom edge with the other gloved hand or forearm. For polished or mitred edges: grip the face of the glass with flat palms using suction-style contact. Never grip a polished edge with bare fingers as if it were raw — even a polished edge can cut under pressure.
6
Lift with your legs, not your backBend at the knees, keep your back straight, and use your leg muscles to rise. Keep the glass close to your body. Do not twist your torso while holding glass — pivot your whole body by moving your feet.
7
Move deliberately and without rushingWalk slowly and steadily. Glass carried on edge is top-heavy and can tip suddenly. Announce your movement — call "Glass moving" so other employees are aware and can clear the path.
8
Two-person carries — designate a leaderOne employee leads the move and calls the actions: "Ready to lift", "Lifting", "Moving", "Setting down". The second person follows the leader's calls. Neither person sets the glass down without a clear verbal agreement from both.
9
Setting glass downSet glass down gently and deliberately. For A-frame or lean racks, lower the bottom edge to the rack first, then lean the piece in at a consistent angle — never let it fall against the rack. Ensure the piece is stable and supported before releasing your grip.
10
Never leave glass unsupported or unattended mid-moveDo not set a piece of glass leaning against a wall, machine, or table edge and walk away. Unsupported glass can and does fall without warning. Always place glass in a proper rack, on a padded table, or hand it directly to another employee.
8. OVERHEAD CRANE & VACUUM LIFTER PROCEDURE
The shop is served by two overhead cranes, each equipped with a vacuum lifter. The crane must be used whenever it is the practical choice for the lift. All operators must be trained and authorised before using the crane independently.
1
Pre-use inspection of the vacuum lifterInspect the suction cups for cracks, tears, or contamination. Confirm all cups seat flat and seal evenly. Verify the vacuum gauge reads in the safe operating range when engaged, and confirm the release handle moves freely. Do not use a lifter with damaged or dirty cups — clean or replace before use.
2
Check the glass surfaceThe vacuum lifter requires a clean, flat, dry surface to achieve a safe seal. Remove any water, grit, oil, or glass dust from the lift area before attaching the cups. Do not attempt to vacuum-lift glass that is wet, heavily contaminated, or has a textured surface that prevents a full seal.
3
Confirm the weight is within the lifter's rated capacityKnow the rated lift capacity of the vacuum lifter in use. Estimate the piece weight (thickness × area × 2.5 kg/m² per mm of thickness). Never exceed the rated capacity. If unsure, ask a supervisor.
4
Attach the lifter centrally and squarelyPosition the lifter centred on the piece, with all cups making contact. Engage the vacuum and confirm the gauge holds in the safe zone before applying any load. If the gauge drops or any cup fails to seal, disengage and reposition.
5
Test lift — raise only a few centimetres firstRaise the piece just a few centimetres off the surface and pause. Confirm the gauge is holding and the piece is hanging level before continuing the lift. If anything seems wrong, lower immediately and investigate.
6
Clear the area under the loadNo employee or bystander may stand under or directly adjacent to a suspended glass load. Call out "Glass in the air" to alert others. Maintain a clear zone around the crane path for the entire duration of the lift.
7
Move slowly and deliberatelyOperate the crane at low speed. Avoid sudden starts, stops, or changes in direction that could cause the glass to swing. Keep the load as low as safely possible during travel.
8
Guide the piece with a hand or tag line — never your bodyIf the glass needs to be rotated or guided into position, use a gloved hand on the face of the glass or a tag line. Never use your body or another person to stop a swinging load.
9
Lower gently and confirm the landing zone is clearConfirm the table, rack, or machine is ready and clear before lowering. Lower slowly until the piece is fully supported, then release the vacuum. Keep hands clear of pinch points between the glass and the receiving surface.
10
Disengage and stow the lifterOnce the glass is safely placed, release the vacuum, remove the lifter, and return it to its home position. Leave the crane in its parked position, not dangling over the work area.
11
Report any vacuum or crane fault immediatelyIf the vacuum gauge fails to hold, a cup leaks, the crane hoist malfunctions, or any abnormal behaviour is observed, take the equipment out of service and notify the supervisor before anyone else uses it.
⚠ WARNING: NEVER stand under a suspended glass load. A vacuum seal can fail without warning. If the gauge drops while a piece is in the air, lower immediately and clear the area.
9. GLASS STORAGE & RACKING
- All glass and mirror must be stored on edge in A-frame or L-shaped glass racks — never stacked flat.
- Racks must be inspected before loading. Do not use a rack with missing padding, broken uprights, or structural damage.
- Store heaviest and largest pieces at the back of the rack; lighter or smaller pieces toward the front.
- Keep pieces of the same thickness and type together where possible to avoid damage from uneven contact.
- Mirror must be stored with its backing facing away from abrasive surfaces. Use cardboard or foam separators between mirror and glass panes in the same rack.
- Never overload a rack beyond its rated capacity. If in doubt, use a second rack.
- Tempered glass must be clearly labelled or separated from non-tempered stock to prevent unintended cutting attempts after tempering.
- Glass leaning against a wall without a proper rack is not acceptable storage — it is a hazard. Use a rack at all times.
10. HOUSEKEEPING & BROKEN GLASS
Routine Housekeeping
- Keep the shop floor clear of glass offcuts, cullet, and dust at all times. These are slip and laceration hazards.
- Sweep glass dust and fine cullet with a broom into a dustpan and dispose of in the designated glass waste bin — not general waste.
- Do not use bare hands to pick up offcuts or cullet — use a brush and dustpan or wear gloves.
Broken Glass Response
- Call out "Glass down" immediately when a breakage occurs so other employees can stop moving and clear the area.
- Do not rush to clean up broken glass. Take a moment to assess the extent of the breakage, particularly for tempered glass which shatters into many small fragments.
- Wear cut-resistant gloves and safety glasses when cleaning up any broken glass.
- Use a broom, not hands, to gather large pieces. Use a wet paper towel or commercial glass pickup pad for fine fragments and slivers.
- Inspect the area thoroughly — glass fragments travel farther than expected. Check machinery, racks, and the floor within a wide radius.
- Report the breakage to the supervisor, including the cause, so it can be recorded and any pattern identified.
