Manufacturing and Heavy Industry

The industry where this work gets deferred longest

Manufacturing plants tend to be well maintained where the machines are and neglected everywhere else. Production equipment gets attention because it stops when it is ignored. Structural steel, overhead, floors, sumps and coatings do not stop, so they get pushed until something forces the issue: an incident, an inspection, an insurance walk, or a customer visit where the building itself became the problem.

That deferral is why the first visit to a plant like this usually finds several years of accumulation and a coating system a decade past its service life. It is also why the honest first conversation is about sequence rather than scope. Everything cannot happen in one shutdown week, and a plan that pretends otherwise gets cut on the day.

What actually needs attention

• Production floors, aisles and walkways carrying oil, coolant and hydraulic fluid
• Machine bases, guarding, housings and the areas underneath them
• Overhead steel, purlins, roof structure, lighting and cable trays
• Ventilation, extraction ducting and weld fume systems
• Coolant sumps, chip pits, floor trenches and containment
• Structural steel, columns, handrails, stairs and platforms
• Exterior walls, docks, canopies and the yard
• Dust collection equipment where the plant generates fines

Floors, slips and the number nobody puts on it

The most common reason a manufacturing plant calls is a floor. Oil, coolant and the film that builds from both turn concrete into a surface that fails the plant’s own safety audit and OSHA’s walking and working surfaces requirement, and the consequence is measured in incidents rather than citations.

The part worth being direct about is that this is an economics question, not a housekeeping one. A slip incident carries a claim, lost time, an investigation and frequently a rate change. Plants that track both numbers generally find that a scheduled degreasing interval costs less than the incidents it prevents, and that is a comparison the plant can make with its own data rather than one Kelly needs to assert.

Where the contamination is continuous because the process has not changed, the answer is an interval rather than a clean. Kelly measures how fast the floor reloads on the first visit and proposes a frequency from that.

Combustible metal dust, which is a different problem

Most combustible dust guidance assumes an organic material. Metal fines do not behave that way, and getting this wrong is dangerous rather than merely ineffective.

Aluminum, magnesium and titanium fines are energetic. Several combustible metals react with water to produce hydrogen, which means that wetting them down, the instinctive response to a dust hazard, can make it worse. Standard vacuum equipment is not appropriate. NFPA 660 absorbed the combustible metals standard for exactly this reason, and the practical consequence is that the material has to be identified before a method is chosen.

Kelly identifies it at the survey. If the plant does not know what its fines are, that is a reason to find out before cleaning, not a reason to proceed carefully and hope. Where the material is a combustible metal, the equipment, tooling and procedure are selected for it specifically.

Coatings, and the difference between paint and protection

A lot of manufacturing plants think of painting as appearance work, and defer it accordingly. On structural steel it is not appearance work. A coating system is the only thing between the steel and corrosion, and corrosion on a column, a platform or a crane runway is a structural matter with a long fuse.

Three things usually justify the spend on their own. Corrosion protection where steel is load bearing or where moisture and chemistry are aggressive. Legibility, because safety markings, aisle lines, hazard identification and equipment labeling stop working when the coating under them fails. And condition assessment, because a coating crew on a lift is frequently the first person to look closely at that steel in years, and what they find goes in the report.

Kelly performs preparation to the standard the specified system requires, which is where most coating failures actually originate, and returns the product data, thickness readings and inspection records.

Using a shutdown week properly

A shutdown week is expensive, short and shared with everyone else who needs access. Most plants under-use it because each scope is procured separately and the conflicts are discovered on site.

Because Kelly performs degreasing, pressure washing, overhead work, pit cleaning and coatings with its own employees, a plant can run several of those on one plan with one point of contact and one crew moving between them in a sequence that makes sense: dry work before wet, overhead before floors, cleaning before coating, and cure time protected rather than compressed. That is worth raising at the survey even when the call was only about the floor.
